Investigating on the electromagnetically induced absorption metamaterial in the terahertz region realized by the multilayer structure

Terahertz Electromagnetically Induced Transparency with Electric-Field-Coupled Inductor-Capacitor Resonators on LCP Substrate

“…Typically, the physical principle of the EIT phenomenon can be described as a threelevel atomic system [37]. In this design, the atomic system composed of the ground state energy |1>, the high energy level |2> and the excitation state energy |3> was mapped to In general, the bending substrate has a remarkable impact on the resonant frequency and the peak value of the transmission peak [32,36].…”

Broadband near unity absorption meta-structure for solar thermophotovoltaic systems and optical window applications

“…Artificially constructed materials, namely meta-structures, meta-materials or meta-surfaces, are widely used for a variety of applications, such as absorbers, [1][2][3] filters, 4 polarization converters, 5 radar systems, 6 microwave imaging, 7 invisible cloaks, 8 sensors, 9,10 polarization converters, 11 telescopes, 12 refractive index sensing, [13][14][15][16][17] and temperature sensing. 18 Notably, meta structures operate in the visible and near-infrared ranges and are also utilized in several applications, including solar energy absorption, 19 blue and ultraviolet light absorbers, 20 photodetector sensors, 21 and optical meta structure-based color transformer systems for fiber optics.…”

“…2 and |r xx (ω)| 2 are the reflectivity of the X polarized wave, while |r xy (ω)| 2 and |r yx (ω)| 2 are the reflectivity of the Y polarized wave. Fig.8(b) depicts the PCR value for both the Y to X polarized wave and the X to Y polarized wave, where the PCR value is obtained near zero in the entire wave range.…”
