Analysis of nonlinear electroelastic continua with electric conduction
… the large deformation theory and the classical Poynting vector based piezoelectric small deformation theory, extended for electric conduction. A result is that electric body forces, realized mathematically as electric surface tractions, are retained in the small deformation approximation. A …

Electromagnetic Vector-Sensor Direction-of-Arrival Estimation in the Presence of Interference
… processing involving a single electromagnetic vector-sensor, with an emphasis on the problem regarding signal-selective narrowband direction-of-arrival (DOA) estimation in the presence of interference. The approach in this thesis relies on a high-resolution ESPRIT-based algorithm. Unlike …

Fundamental Limits on Antenna Size for Frequency and Time Domain Applications
… through investigating impedance, power, the Poynting vector, and energy velocity of a radiating antenna. Antenna transfer functions were investigated to understand the real-world challenges in antenna design and overall performance. An extended model, using both the singularity expansion …

Automating Pre-Stack Migration Enhancement and Image Quality Analysis
… migration images by comparing the processed Poynting-vector reverse time migration (PVRTM) images with reverse time migration (RTM) used Laplacian filter and partial stacked PVRTM. These comparable migration images are benchmarked against the synthetic reflector model being used as a …

On the parallels between the Maxwell and Dirac equations
… to the rapidly oscillating part of the Poynting vector in classical electromagnetism. Both the Maxwell and Dirac equations can be reformulated into closely related quaternionic equations, which directly reveal the difference in how these equations transform under Lorentz transformations. …

Characterisation of silicon photonics devices
… photonics. Initially in this work, a fully vectorial H-field based finite element method has been used to obtain the modal characteristics of high index contrast bent waveguide to get a better understanding of the curved section. Through the beam propagation method, the propagation losses …
