Characterization of Surface Electromagnetic Waves and Scattering on Infrared Metamaterial Absorbers
Wen-Chen Chen, Machhindra Koirala, Xianliang Liu +7
We report, for the first time, a full experimental and computational investigation of all possible light matter interactions on the surface of an infrared metamaterial absorber (MM…
Liquid Crystal Tunable Metamaterial Perfect Absorber
David Shrekenhamer, Wen-Chen Chen, Willie J. Padilla
We present experimental demonstration of electronically tunable metamaterial perfect absorbers in the terahertz regime. By incorporation of active liquid crystal into strategic loc…
Loss compensation in Metamaterials through embedding of active transistor based negative differential resistance circuits
Wangren Xu, Willie J. Padilla, Sameer Sonkusale
This paper presents an all-electronic approach for loss compensation in metamaterials. This is achieved by embedding active-transistors based negative differential resistance (NDR)…
