Common Mode Mitigation by Applying Absorber with Genetic-Algorithm Optimized Cross-Section to Microstrip Pair (Published in: 2021 IEEE International Joint EMC/SI/PI and EMC Europe Symposium)
At the post-design stage, applying absorber to transmission lines is a cost-effective and efficient way to improve the EMI behavior of a product. This work presents an optimized shape of absorber that can be applied to a microstrip pair. The presented shape is an outcome of Genetic-Algorithm Optimization. It mitigates EMI by increasing common mode insertion loss of the microstrip pair while maintaining the differential mode signal integrity. Measurements are conducted to prove the superiority of the optimized shape of absorber.
Inverse Design Shape Optimized 1x2 Multimode Interference Coupler (FDTD Project at University of Southern California)
Project is based around the design of a planar 1:2 optical waveguide splitter using inverse design techniques to determine the best waveguide parameters for optimized performance. The
output channel of the splitter can be controlled by injecting TE or TM polarized waves. Optical waveguide splitter technology is widely used in silicon photonics applications.
The breakdown of the project is as follows:
a. Code a 2D FDTD implementation with PML.
b. Implement a 1D mode solver to solve for modes of 2D dielectric waveguides.
c. Implement code to excite modes in a dielectric waveguide.
d. Simulate a 1:2 waveguide splitting structure.
e. Design code using the adjoint method to obtain the gradient and use this to optimize the dielectric shape of the splitter to maximize throughput.
Universal Termination System for Power Tools
Patent US PCT/US2006/018105 · Issued Nov 5, 2006
A universal termination system (700) is provided for power tools. The universal termination system includes criteria for each of the main switch platforms that define the number, type, location and orientation of the terminations (702,706). That is, the number, type, location and orientation of the terminations in each main switch platform are standardized and the power tools that use that type main switch platform use the main switch platform having standardized terminations.
