Equalized Time Reversal Beamforming for Indoor Wireless Communications
Carlos A. Viteri-Mera, Fernando L. Teixeira
Time-reversal (TR) is a beamforming technique for frequency-selective channels, which has received increasing attention due to its high energy efficiency and low computational comp…
Exact Charge-Conserving Scatter-Gather Algorithm for Particle-in-Cell Simulations on Unstructured Grids: A Geometric Perspective
Haksu Moon, Fernando L. Teixeira, Yuri A. Omelchenko
We describe a charge-conserving scatter-gather algorithm for particle-in-cell simulations on unstructured grids. Charge conservation is obtained from first principles, i.e., withou…
Computation of potentials from current electrodes in cylindrically stratified media: A stable, rescaled semi-analytical formulation
Haksu Moon, Fernando L. Teixeira, Burkay Donderici
We present an efficient and robust semi-analytical formulation to compute the electric potential due to arbitrary-located point electrodes in three-dimensional cylindrically strati…
Perfectly Reflectionless Omnidirectional Absorbers and Electromagnetic Horizons
Kamalesh Sainath, Fernando L. Teixeira
We demonstrate the existence of metamaterial blueprints describing, and fundamental limitations concerning, perfectly reflectionless omnidirectional electromagnetic absorbers (PR-O…
Spectral-Domain-Based Scattering Analysis of Fields Radiated by Distributed Sources in Planar-Stratified Environments with Arbitrarily Anisotropic Layers
Kamalesh Sainath, Fernando L. Teixeira
We discuss the numerically stable, spectral-domain computation and extraction of the scattered electromagnetic field excited by distributed sources embedded in planar-layered envir…
Tensor Green's Function Evaluation in Arbitrarily Anisotropic, Layered Media using Complex-Plane Gauss-Laguerre Quadrature
Kamalesh Sainath, Fernando L. Teixeira
We discuss the application of Complex-Plane Gauss-Laguerre Quadrature (CGLQ) to efficiently evaluate two-dimensional Fourier integrals arising as the solution to electromagnetic fi…
