AbstractIn this thesis, a short film titled “Engineering with a Purpose: Nontraditional Perspectives” is produced. A film written, edited, and produced by a mechanical engineering undergraduate was something outside of the norm for a final report. In order to successfully create a film, research on the types and style of films was performed. Movavi Editor software was utilized for purposes of editing. This film challenges perspectives and opens eyes to the cross-disciplinary skills engineering requires while drawing attention to the lessons engineers can learn from other disciplines. The meaning, history and stereotypical views that engineering possesses is expressed. The correlations between philosophy and engineering are filmed with an Ancient Greek Socratic lens. The challenges women must overcome in a predominantly male field are conveyed. Inspirational and telling clips to encourage young women considering engineering concludes this portion of the film. Art and engineering is also expressed through the opportunities 3D manufacturing provides. The film is concluded with multiple languages to open the audience eyes that the basis of engineering, problem solving, is nondiscriminatory. The film’s mission is to inspire non-engineers about how they can relate to engineering practice while motivating current engineers to never give up. It also draws attention to the role an engineer plays in society for progress and future development. Creating a film was a whole design process that required countless iterations. Motivation for this film stemmed from professional opportunities with a mechanical engineering degree and the potential positive impacts and purposeful work engineering requires.

Acoustical test chamberCabuk, Cansu (2018-05)The purpose of this project is to create an acoustical test chamber for use by students and faculty of the Division of Engineering Programs at SUNY New Paltz. An acoustical test chamber is a controlled environment that is instrumented with a microphone array. This allows the user to perform accurate acoustical measurements on sound sources without outside interference while also dampening internal sound. These measurements will help the user determine vital sound parameters and display information relating to the sound signal. The properties of sound that are measured include sound intensity and sound frequency. Sound frequency information is plotted and displayed using a spectrogram. In addition, a sound localization feature using time difference of arrival estimation was implemented into the chamber’s functionality. The sound is measured using four electret microphones, then transferred to a computer utilizing stereo microphone inputs. The computing environment, MATLAB, and its functions were utilized by establishing a user friendly, interactive interface between the sensor hardware and the test environment. MATLAB’s functions and Graphical User Interface (GUI) feature, proved to be critical tools in simplifying the data acquisition, algorithmic and display processes. Before final construction, the sound location feature produced results with an average of 17% error. While after final construction, the number of trials that produced feasible results decreased drastically. This may be down to slight changes in the array geometry during the chamber’s construction process. This project is important as it provides engineering students at SUNY New Paltz, an opportunity to further enhance their exposure to acoustical testing techniques. The sound chamber will be used to verify analysis techniques learned in the classroom, in addition to providing research opportunities to students. However, the sound location feature is inadequate and still needs development.
3-D printed heterogenous substrate bandpass filtersNesheiwat, Issa (2021-09)With the demand for increasing frequencies in today’s communications systems, compact integrated circuits are challenging to achieve. Compact filters have typically been realized by modifying the circuit design including using LC resonators, defective ground structures, and adjusting the length ratios of resonators. Heterogenous substrates with controlled regions of dielectric loading offer a new design approach when it comes to manufacturing an RF component. In this thesis, additive manufacturing is used to selectively place low-K and high-K dielectric materials to achieve a compact form factor, improved bandwidth, and higher suppression in re-entry modes. First, microstrip coupled strip lines are simulated to model the basic coupling effects of loading a substrate. Next, three 2.45GHz parallel coupled bandpass microstrip filters are designed with differing substrates: low-K, high-K and high-K loaded to analyze the impact of loading within the substrate. The filter substrates are manufactured using a dual-extrusion FDM 3-D printer to combine both dielectrics, low-K ABS, and high-K PrePerm ABS1000, into a single heterogeneous substrate. Compared to the low-K dielectric alternative, the high-K loaded filter demonstrated a 30.8% decrease in length, while maintaining similar bandwidth and suppression of re-entry modes. Compared to the high-K filter, the high-K loaded filter showed a 9.4dB reduction in re-entry mode suppression, while maintaining similar footprint size.
Analysis of ground plane size, topography and location on a monopole antenna's performance utilizing 3-D printingCiraco, Vito (2021-09)The monopole antenna is widely used in communication applications and is typically mounted on various surfaces that act as ground planes; a prime example being the roof of a car. The shape of the ground plane can drastically change the patterns of the electromagnetic radiation of a monopole antenna as well as its RF performance. Extensive work [1,12-13] has been done on the numerical modeling of arbitrarily shaped ground planes. However, due to their geometric complexity, there is very little work reported on the practical testing component of physical antennas with these obscure ground plane structures. This thesis illustrates how the additive manufacturing process presented can be used to physically realize arbitrarily shaped ground planes and provides a low-cost process to verify the numerical model. Ground Planes were modified while maintaining the same antenna length to evaluate the impact on antenna performance. The antenna was not optimized or changed to a standard antenna design. Varying radius spherical ground planes are modelled, as well as modified ground plane structures to evaluate the impact of the ground plane on a 1.3GHz monopole antenna's performance and in some cases to modify the antenna's performance in terms of gain, bandwidth, and radiation pattern. Designs such as the planar ground with horn was found to enhance monopole bandwidth by more than 5 times that of a standard planar ground but significantly deteriorate the antenna's radiation pattern. Moreover, complex geometry such as the fin sphere ground plane offered a 25% increase in gain relative to the standard sphere ground. Designs like the edge-mounted sphere can offer directive gain and radiation characteristics simply by altering the antennas' location mount location with respect to its ground plane. The techniques presented in this thesis offer new ways of producing 3-D printed ground planes for RF applications that are easier to manufacture, lighter in weight, and can enhance antenna performance over their conventional counterparts.
