Wide-Band/Angle Blazed Dual Mode Metallic Groove Gratings
Omid Hemmatyar, Mohammad Ali Abbassi, Babak Rahmani +2
We introduce a new and simple approach to acquire wide-band/angle blazing operation in one-dimensional metallic gratings supported by equivalent circuit analysis. The gratings that…
Non-reciprocity using quadrature-phase time-varying slab resonators
Mahdi Chegnizadeh, Mohammad Memarian, Khashayar Mehrany
In this paper, it is shown that non-reciprocity can be observed in time-varying media without employing spatio-temporal modulated permittivities. We show that by using only two one…
Inclusion of the backaction term in the total optical force exerted upon Rayleigh particles in nonresonant structures
Mohammad Ali Abbassi, Khashayar Mehrany
In this paper, we investigate the impact of the electromagnetic scattering caused by other objects in nonfree space on the time averaged force exerted upon a Rayleigh particle, whi…
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…
