All-Dielectric Nanophotonic via Glass Fluid Instabilities

In this thesis work, we propose to exploit an innovative micro/nano-fabrication process, based on controlled fluid instabilities of a thin viscous film of chalcogenide glass. Amorphous selenium and arsenic triselenide were used in this thesis work, and com ...

Improving the radiation characteristics of shorted annular ring antennas through symmetric aperture-coupled feeding

Anja Skrivervik, Hannes Bartle

In this paper, a novel feeding method for shorted annular ring (SAR) antennas is presented. SAR antennas can be designed to not excite surface waves and hence have desirable properties for many applications. The traditional method of feeding a SAR is throu ...
