Electromagnetic Field Manipulation: Biosensing to Antennas


Sideris, Constantine (2017) Electromagnetic Field Manipulation: Biosensing to Antennas. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/Z9RN35XW.


We will explore how understanding and controlling electromagnetic fields can provide significant impact across a multitude of applications throughout the whole frequency spectrum from DC to daylight. Starting from the DC end of the electromagnetic spectrum, we motivate the design of a new integrated magnetic biosensing design as well as various improvements to the initial design based on spatial and temporal manipulations of the magnetic fields. Next, we look into the RF domain and develop maximal performance bounds for antennas and other electromagnetic structures. We develop rapid simulation techniques which when coupled with heuristic optimization algorithms can quickly and effectively produce new antenna structures with little to no manual intervention. We demonstrate the efficacy of these techniques in the context of on-chip antenna designs and a 3D printed coupling antenna for a dielectric waveguide communication link. We present the design of a 120GHz dual-channel 100Gbps QPSK/64QAM transceiver IC developed in a standard 28nm bulk CMOS process. Finally, we explore the higher THz regime in the context of photonic device optimization. We optimize compact photonic multiplexer devices which are fabricated in a standard foundry process and evaluate their performance against simulation results.
