Scattering and Optimization Methods for Radar and Millimeter Wave Applications
… arising application of EM analysis is the microwave design. Bayesian Optimization is a machine learning based method that enables fast convergence toward a global optimum. A general problem with this method is the low dimensionality of the problem that needs to be addressed which is …

Parallel Computational Approach to Gradient Based EM Optimization of Microwave Structures
Electromagnetic (EM) based optimization and design closure is an essential part of RF and microwave design cycle. The main objective of this thesis is to develop a new gradient based EM optimization technique which exploits parallel computations. The proposed EM optimization technique achieves …

Multiband RF/Microwave Front-end Receiver Design for Multi-Standard Applications
… and low feasibility for high integration design. Compared to the RF transmitter, the design of the RF receiver front end is considered to be more challenging due to the increased signal interference/noise in the communication path, which often can be neglected in transmitter design due to …

Slow-wave electrode structures for III-V semiconductor based electro-optic travelling-wave modulators
… created by the velocity-mismatch between the microwave modulating signal and the optical signal (or equivalently, the mismatch between the effective refractive indices of the microwave and the optical wave). These problems ultimately limit the modulator bandwidth and require large amounts of …

A Novel Unit Cell Antenna for Highly Integrated Phased Arrays in the SHF Band
… <p>On a prior effort, an integrated unit cell design was developed for a PCB-based SATCOM array application. However, the design failed to meet the requirements. The primary objective of this work is to demonstrate an improved design using systematic microwave design techniques and modern …
