PlanOpSim InverseMeta
Our project concentrates on using PlanOpSim’s optimization algorithm software to enhance the efficiency and functionality of nanostructured optical devices. Unlike traditional engineering methods, in which a structure is designed and then tested, inverse design begins with a target optical response and uses computational methods to determine the optimal nanostructure to achieve that function. For our first objective, we designed a metasurface capable of displaying two distinct holographic images depending on whether the incident light is in the TE or TM polarization state. For the second, we aimed to design a metasurface that produces specific colors by controlling the interaction of light with carefully engineered nanostructures.
ASML FIBER
The low numerical aperture multimode fiber project is a detailed fiber design and simulation developed by a team of undergraduate senior students. As such, the inputs were determined through discussion with our project customer, ASML. We are designing a fiber to support ASML’s YieldStar (YS) optics sensor for scanning wafers using white light with the wavelength range of 400 to 1000 nm and another fiber to operate at a wavelength of 1070 nm meant to preheat a mirror for a separate lithography machine.

Water Tow Tank
Tow Tank devices are used in testing boat and aerodynamic models for things like aerodynamic drag and lift. These devices typically cost around $20,000 which is the reason not every school has access to such a device. Here in the University of Rochester, we don't have our own tow tank device, but we do have a swimming pool, and a passion for solving problems. In this post, we are showcasing our prototype for a tow tank that can be assembled and used in the gym swimming pool. The cost of the prototype and the completed final device is less than $1000!
Ugandan Water Project
The main goal of this project is to build, assemble, and successfully test an accelerated testing machine for the India Mark II. In the India Mark II pump, the water gaskets wore off frequently during the pumping of water and needed frequent replacement which proved costly. To counter the problem, the project below proposes an accelerated testing machine composed of a slider-crank mechanism. The mechanism incorporated a flywheel driven by a motor that ensures continuous harmonic motion that replicates pumping mechanisms in the field. The mechanism was designed, simulated and a finite element analysis carried out in CAD software. These are covered in the report along with testing results and recommendations provided for improvement of future designs.​
Turing Machine
Modern mechanical engineers utilize computers but do not fully understand how the computer performs its computations. Understanding the fundamentals will give them a better understanding to the limitation of traditional computing. To address this gap between functionality and understanding, we built a 4ft by 6ft physical 3-bit adder to blow up the tiny processes that go on inside of a computer. Using a system of logic gates, where marbles act as inputs and outputs, our machine is able to add numbers 7 and below to each other and produce an output in binary.

Cautery Phantom
The cautery phantom senior design team will engineer and improve a system that will arrest artificial blood flow in response to electrocautery in a tissue phantom manufactured by Simulated Inanimate Models, LLC (SIM). To solve this problem, we have investigated methods of vessel constriction by lining the tissue phantom blood vessel wall with a thermoresponsive material, coagulating the artificial blood by introducing proteins and chemicals into the mixture, and by making the blood vessel with a shape memory polymer.
