Genetic Algorithm-Based Inverse Design of Guided Wave Planar Terahertz Filters
Ali Dehghanian, Thomas Darcie, Levi Smith
We present a genetic algorithm (GA)-based inverse design framework for synthesizing high-performance planar terahertz (THz) filters integrated with coplanar striplines (CPSs). The…

Demonstration of a planar multimodal periodic filter at THz frequencies
Ali Dehghanian, Mohsen Haghighat, Thomas Darcie +1
This paper presents a planar multimodal periodic filter that is constructed from alternating sections of coplanar stripline and the odd-mode of a finite-ground plane coplanar waveg…
