Cross‐coupled dielectric waveguide filter
International journal of RF and microwave computer-aided engineering, 2021 A cross‐coupled dielectric waveguide filter based on blind holes and via holes is proposed in this study. Using a unique all‐hole design, a fourth‐order cross‐coupled dielectric waveguide bandpass filter is realized by drilling via holes or blind holes ...

Fluorescence Spectroscopy with Metal–Dielectric Waveguides [PDF]
The Journal of Physical Chemistry C, 2015 We describe a hybrid metal-dielectric waveguide structures (MDWs) with numerous potential applications in the biosciences. These structures consist of a thin metal film coated with a dielectric layer. Depending on the thickness of the dielectric layer, the modes can be localized near the metal, within the dielectric, or at the top surface of the ...
