Bayesian compressive sensing for ultrawideband inverse scattering in random media
A. E. Fouda, F. L. Teixeira
We develop an ultrawideband (UWB) inverse scattering technique for reconstructing continuous random media based on Bayesian compressive sensing. In addition to providing maximum a…
Complex-Plane Generalization of Scalar Levin Transforms: A Robust, Rapidly Convergent Method to Compute Potentials and Fields in Multi-Layered Media
Kamalesh Sainath, Fernando Teixeira, Burkay Donderici
We propose the complex-plane generalization of a powerful algebraic sequence acceleration algorithm, the Method of Weighted Averages (MWA), to guarantee exponential-cum-algebraic c…
Robust Computation of Dipole Electromagnetic Fields in Arbitrarily-Anisotropic, Planar-Stratified Environments
K. Sainath, F. L. Teixeira, B. Donderici
We develop a general-purpose formulation, based on two-dimensional spectral integrals, for computing electromagnetic fields produced by arbitrarily-oriented dipoles in planar-strat…
Stable pseudoanalytical computation of electromagnetic fields from arbitrarily-oriented dipoles in cylindrically stratified media
H. Moon, F. L. Teixeira, B. Donderici
Computation of electromagnetic fields due to point sources (Hertzian dipoles) in cylindrically stratified media is a classical problem for which analytical expressions of the assoc…
Metamaterial Loadings for Waveguide Miniaturization
H. Odabasi, F. L. Teixeira
We show that a rectangular metallic waveguide loaded with metamaterial elements consisting of electric-field coupled (ELC) resonators placed at the side walls can operate well belo…
Causal--Path Local Time--Stepping in the Discontinuous Galerkin Method for Maxwell's equations
L. D. Angulo, J. Alvarez, F. Teixeira +2
We introduce a novel local time-stepping technique for marching-in-time algorithms. The technique is denoted as Causal-Path Local Time-Stepping (CPLTS) and it is applied for two ti…
Random Lattice Gauge Theories and Differential Forms
F. L. Teixeira
We provide a brief overview on the application of the exterior calculus of differential forms to the ab initio formulation of field theories on random simplicial lattices. In this…
