Launching and Controlling Gaussian Beams from Point Sources via Planar Transformation Media
Hayrettin Odabasi, Kamalesh Sainath, Fernando L. Teixeira
Based on operations prescribed under the paradigm of Complex Transformation Optics (CTO) [1-5], it was recently shown in [5] that a complex source point (CSP) can be mimicked by a…
Interface-Flattening Transform for EM Field Modeling in Tilted, Cylindrically-Stratified Geophysical Media
Kamalesh Sainath, Fernando L. Teixeira
We propose and investigate an "interface-flattening" transformation, hinging upon Transformation Optics (T.O.) techniques, to facilitate the rigorous analysis of electromagnetic (E…
