Reconfigurable Intelligent Surfaces: Interplay of Unit-Cell- and Surface-Level Design and Performance under Quantifiable Benchmarks
Ammar Rafique, Naveed Ul Hassan, Muhammad Zubair +5
The ability of reconfigurable intelligent surfaces (RIS) to produce complex radiation patterns in the far-field is determined by various factors, such as the unit-cell's size, shap…
Unraveling the vector nature of generalized space-fractional Bessel beams
Aqsa Ehsan, Muhammad Qasim Mehmood, Kashif Riaz +2
We introduce an exact analytical solution of the homogeneous space-fractional Helmholtz equation in cylindrical coordinates. This solution, called vector Space-Fractional Bessel Be…
Long distance adiabatic wireless energy transfer via multiple coils coupling
Wei Huang, Xiaowei Qu, Shan Yin +4
Recently, the wireless energy transfer model can be described as the Schrodinger equation [Annals of Physics, 2011, 326(3): 626-633; Annals of Physics, 2012, 327(9): 2245-2250]. Th…
Frequency Diverse Array Radar: New Results and Discrete Fourier Transform Based Beampattern
Muhammad Zubair, Sajid Ahmed, Mohamed-Slim Alouini
In the phased-array radar (PAR) signals from each antenna are transmitted at the same carrier frequency, which yields narrowly focused only angle dependent beampattern. In contrast…
Fractional Fresnel coefficients for optical absorption in femtosecond laser-induced rough metal surfaces
Muhammad Zubair, Yee Sin Ang, Kelvin J. A. Ooi +1
The surface morphology of metal influences its optical absorptivity. Recent experiments have demonstrated that the femtosecond laser induced surface structures on metals could be d…
