Interactions of electromagnetic wave with epsilon-near-zero (ENZ) bilayer planar thin films have been extracted in near-infrared. The ENZ material properties are harnessed theoretically as broadband and narrowband coherent perfect absorption (CPA). A

We analyze the coherent perfect absorption (CPA) in unpatterned thin films in intrinsic semiconductor using the admittance matching method. The CPA is obtained at the phase and irradiance matching conditions. Controlling the modulation of relative in

Perfect absorption is one of the important application of epsilon-near-zero (ENZ) material. We analyze here the coherent perfect absorption (CPA) in single and bilayer of ENZ thin film of ITO by admittance matching method. To enhance the absorption,

We propose a general, easy-to-implement scheme for broadband coherent perfect absorption (CPA) using epsilon-near-zero (ENZ) multilayer films. Specifically, we employ indium tin oxide (ITO) as a tunable ENZ material, and theoretically investigate CPA
