Resonant field enhancement near bound states in the continuum on periodic structures
Zhen Hu, Lijun Yuan, Ya Yan Lu
On periodic structures sandwiched between two homogeneous media, a bound state in the continuum (BIC) is a guided Bloch mode with a frequency within the radiation continuum. BICs a…
Perturbation theories for symmetry-protected bound states in the continuum on two-dimensional periodic structures
Lijun Yuan, Ya Yan Lu
On dielectric periodic structures with a reflection symmetry in a periodic direction, there can be antisymmetric standing waves (ASWs) that are symmetry-protected bound states in t…
Bound states with complex frequencies near the continuum on lossy periodic structures
Zhen Hu, Lijun Yuan, Ya Yan Lu
On a lossless periodic dielectric structure sandwiched between two homogeneous media, bound states in the continuum (BICs) with real frequencies and real Bloch wavevectors may exis…
Unidirectional Reflectionless Transmission for Two-Dimensional -symmetric Periodic Structures
Lijun Yuan, Ya Yan Lu
Unidirectional reflectionless propagation (or transmission) is an interesting wave phenomenon observed in many -symmetric optical structures. Theoretical studies on u…
Excitation of bound states in the continuum via second harmonic generations
Lijun Yuan, Ya Yan Lu
A bound state in the continuum (BIC) on a periodic structure sandwiched between two homogeneous media is a guided mode with a frequency and a wavenumber such that propagating plane…
