Bound states in the continuum and exceptional points in dielectric waveguide equipped with a metal grating
Ryo Kikkawa, Munehiro Nishida, Yutaka Kadoya
Bound states in the continuum (BICs) and exceptional points (EPs) have been the subjects of recent intensive research as they exhibit exotic phenomena that are significant for both…

Polarization-based branch selection of bound states in the continuum in dielectric waveguide modes anti-crossed by a metal grating
Ryo Kikkawa, Munehiro Nishida, Yutaka Kadoya
We investigate bound states in the continuum (BICs) in a planar dielectric waveguide structure consisting of a gold grating on a dielectric layer with a back layer of metal. In thi…
