Analog Optical Implementation of Spatial High Pass Filtering Using Evanescent Waves
Ali Pour Mohammad Qoli Vafa, Parisa Karimi, Amin Khavasi
We introduce optical polarization-insensitive high pass filters based on total internal reflection of light at the interface of two dielectric media (1D) and Bragg reflection of a…

Wideband Antireflection Coating Using Metamaterials
Fahimeh Sepehripour, Parisa Karimi, Amin Khavasi
In this paper, we propose a new approach for realizing antireflection coating using metamaterials. In this approach, a subwavelength array of metallic pillars (with square cross-se…
