Unidirectional reflectionless propagation in non-Hermitian metamaterial based on phase coupling between two resonators
2018
Abstract Unidirectional reflectionless propagation in a non-Hermitian metamaterial is obtained based on phase coupling between two resonators. The unidirectional reflectionless propagation can be obtained at exceptional point by adjusting polarization angle θ and distance d between two resonators. Moreover, coherent prefect absorptions are obtained near exceptional point with the high absorbance of ∼ 0.99 and high quality factor of ∼ 83.
