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 theta and distance d between two resonators. Moreover, coherent prefect absorptions are obtained near exceptional point with the high absorbance of similar to 0.99 and high quality factor of similar to 83. (C) 2018 Elsevier B.V.
