Three-dimensional Electromagnetic Void Space
Changqing Xu, Hongchen Chu, Jie Luo +3
We report a realization of three-dimensional (3D) electromagnetic void space. Despite occupying a finite volume of space, such a medium is optically equivalent to an infinitesimal…
Breakdown of Maxwell Garnett theory due to evanescent fields at deep-subwavelength scale
Ting Dong, Jie Luo, Hongchen Chu +2
Deep-subwavelength all-dielectric composite materials are believed to tightly obey the Maxwell Garnett effective medium theory. Here, we demonstrate that the Maxwell Garnett theory…
Pseudo-Hermitian Systems Constructed by Transformation Optics with Robustly Balanced Loss and Gain
Liyou Luo, Jie Luo, Hongchen Chu +1
Non-Hermitian systems with parity-time symmetry have been found to exhibit real spectra of eigenvalues, indicating a balance between the loss and gain. However, such a balance is n…
Ultra-broadband reflectionless Brewster absorber protected by reciprocity
Jie Luo, Hongchen Chu, Ruwen Peng +3
The Brewster's law predicts zero reflection of p-polarization on a dielectric surface at a particular angle. However, when loss is introduced into the permittivity of the dielectri…
