"This book investigates analytical techniques encompassing the linear modelling of passive and active - in particular FET - structures. This book was primarily conceived as a bridge between the mathematical abilities of the pure EM theorist and those of the FET circuit modeller.…
Novel metamaterial and metamaterial-inspired structures and microwave/antenna applications thereof are proposed and studied in this thesis. Motivated by the challenge of extending the applicability of metamaterial structures into practical microwave solutions, the underlying obj…
Carbon nanotube (CNT) composites have been of significant research interest in a wide range of applications. For electromagnetic applications, simplifying assumptions regarding the distribution and shapes of the CNTs are typically made because the exact three-dimensional CNT dis…
In this dissertation, a core design is proposed to minimize the core loss of a high-power wireless charging system (WCS). The core-loss characteristics are investigated through finite element analysis (FEA). Compared to the traditional uniform thickness core, in the proposed cor…
Recently, on-chip comb generation methods based on nonlinear optical modulation in ultrahigh quality factor monolithic micro-resonators have been demonstrated. In these methods, two pump photons are transformed into sideband photons in a four wave mixing process mediated by the …
This book presents the application of the overlapping grids approach to solve chiral material problems using the FDFD method. Due to the two grids being used in the technique, we will name this method as Double-Grid Finite Difference Frequency-Domain (DG-FDFD) method. As a resul…
This work is presented in three chapters. Chapter 1 is an introduction containing a brief history of electronics and instrumentation lab courses taught at universities. It covers the current state of affairs of the lab class Phys 311: Electronics for Scientists, taught at SDSU, …
James Clerk Maxwell's theories of electromagnetism are uniquely Victorian products. Maxwell and his physics have traditionally been viewed as aloof and disinterested, dating to the mid-to-late-19th century, but not party to the cultural, industrial, political, economic, and envi…
Investigating the Earth’s magnetic field provides a unique window into the history of Earth’s outer core, where the field is generated. Rocks gain a magnetization that is in the direction of and proportional to the Earth’s magnetic field at the time of their formation, such as w…
Understanding electron properties in space plasma environments is crucial in understanding how various space plasmas evolve and interact with different obstacles, such as the difference between intrinsically unmagnetized (Mars) and intrinsically magnetized (Earth). However, care…
Advances in materials research and manufacturing techniques are rapidly allowing more complex and interesting functional electromagnetic applications to be brought to fruition. Electromagnetic application development within all frequency bands ranging from infrared to radio and …
Most of the baryons, or “normal" matter, found in galaxies and galaxy clusters are found in the hot, X-ray emitting gas known as the circumgalactic medium (CGM) or intracluster medium (ICM). The hot gas traces the gravitational potential well and is affected by both thermal and …
Over the past decade, large photometric surveys, and more recently spectroscopic follow up, have elucidated a clearer picture of galaxy evolution since the epoch of peak star formation at z = 1-3. However, despite these advancements, low mass galaxies, which exhibit much higher …
One of the best tools we have for the edification of physics is the analogy. When we take our classical set of states and dynamical variables in phase space and treat them as vectors and Hermitian operators respectively in Hilbert space through the canonical quantization, we los…
