Nonreciprocal Local-Resonance Induced Complex Band Hybridization
Wang Tat Yau, Kai Fung Lee, Raymond P. H. Wu +4
We study the complex band hybridization induced by nonreciprocal local resonances in photonic crystals. Composed of trimer unit cells, a two-dimensional (2D) magnetophotonic crysta…

Topological Theory for Perfect Metasurface Isolators
Wai Chun Wong, Wenyan Wang, Wang Tat Yau +1
We introduce topological theory of perfect isolation: perfect transmission from one side and total reflection from another side simultaneously. The theory provides an efficient app…
