Broadband, Polarization-insensitive and Wide-angle Optical Absorber based on Fractal Plasmonics
Ali Eshaghian, Sajjad AbdollahRamezani, Ata Chizari +1
In this paper, a plasmonic absorber consisting of a metal-dielectric-metal stack with a top layer of Sierpinski nanocarpet is theoretically investigated. Such compact absorber depi…
Analog Optical Computing Based on Dielectric Meta-reflect-array
Ata Chizari, Sajjad AbdollahRamezani, Mohammad Vahid Jamali +1
In this paper, we realize the concept of analog computing using an array of engineered gradient dielectric meta-reflect-array. The proposed configuration consists of individual sub…
Analog computing by Brewster effect
Amir Youssefi, Farzad Zangeneh-Nejad, Sajjad AbdollahRamezani +1
Optical computing has emerged as a promising candidate for real-time and parallel continuous data processing. Motivated by recent progresses in metamaterial-based analog computing…
Mining DNA Sequences Based on Spatially Coded Technique Using Spatial Light Modulator
Masoome Fazelian, Sajjad AbdollahRamezani, Sima Bahrani +6
In this paper, we present an optical computing method for string data alignment applicable to genome information analysis. By applying moire technique to spatial encoding patterns…
Statistical Distribution of Intensity Fluctuations for Underwater Wireless Optical Channels in the Presence of Air Bubbles
Mohammad Vahid Jamali, Pirazh Khorramshahi, Arvin Tashakori +6
In this paper, we experimentally investigate the statistical distribution of intensity fluctuations for underwater wireless optical channels under different channel conditions, nam…
