The Systematic Design of Non-commensurate Impedance Matching Tapers for Ultra Wideband Gradient-Index (GRIN) Lens Antennas
Wei wang, Nicolas Garcia, Jonathan Chisum
We propose a general method for designing wideband matching tapers in inhomogeneous media where phase velocity is coupled to the taper impedance profile. Such tapers are used to ma…

High-efficiency, Wideband GRIN Lenses with Intrinsically Matched Unit-cells
Nicolas Garcia, Jonathan Chisum
We present an automated design procedure for the rapid realization of wideband millimeter-wave lens antennas. The design method is based upon the creation of a library of matched u…

Silicon Micromachined High-contrast Artificial Dielectrics for Millimeter-wave Transformation Optics Antennas
Nicolas Garcia, Wenlong Bai, Thibault Twahirwa +2
Transformation optics methods and gradient index electromagnetic structures rely upon spatially varied arbitrary permittivity. This, along with recent interest in millimeter-wave l…
