Effect of Substrate Thickness on Responsivity of Free-Membrane Bolometric Detectors
Mehdi Hosseini, Alireza Kokabi, Ali Moftakharzadeh +2
The effect of substrate thickness and its Debye temperature on the bolometric response of the freestanding-membrane type of superconductor transition-edge detectors is investigated…
Compound Hertzian Chain Model for Copper-Carbon Nanocomposites' Absorption Spectrum
Alireza Kokabi, Mehdi Hosseini, Saman Saeedi +3
The infrared range optical absorption mechanism of Carbon-Copper composite thin layer coated on the Diamond-Like Carbon (DLC) buffer layer has been investigated. By consideration o…
Photonic band-structure and optical S-matrix analyses of the proposed superconducting nanostructures
Ali Sobhani Khakestar, Alireza Kokabi, Khashayar Mehrany +1
Special optical structures composed of superconducting nanostructure based on the elemental type-II and layered high-Tc superconductors are proposed. The photonic band structure an…
