High-performance nanophotonic devices require extreme depth-to-diameter ratios, which are notoriously difficult to fabricate.
Abstract: A new slab waveguide integrated in planar form has been developed for wideband microwave applications. The guide is synthesized on a substrate by adding an air hole into an SIW (substrate ...
Abstract: A novel phase corrected substrate integrated waveguide (SIW) H-plane horn antenna with embedded metal-via arrays is presented. The SIW horn is divided into four subhorns by three metal-via ...
