Abstract
Waveguides and electromagnetic cavities fabricated in hyperuniform disordered materials with complete photonic bandgaps are provided. Devices comprising electromagnetic cavities fabricated in hyperuniform disordered materials with complete photonic bandgaps are provided. Devices comprising waveguides fabricated in hyperuniform disordered materials with complete photonic bandgaps are provided. The devices include electromagnetic splitters, filters, and sensors.
Claims3
A device comprising a plurality of waveguides disposed at arbitrary angles with respect to one another and phononic communication, wherein the communication takes place at a junction of the waveguides, wherein the device is configured such that a spectrum of acousto-elastic waves enters through one arm and is divided at the junction into different frequency bands, each of which is directed into different arms.
