The Möbius strip, a twisted loop with one continuous surface, is inspiring chemists to create novel molecular structures. A team has synthesized a type of carbon-based molecule with an unprecedented ...
Abstract: Analytical expression of transmission for the orbital angular momentum (OAM) communication using loop antenna arrays and paraboloids is derived to achieve a communication distance of 100 m.
Abstract: This paper presents a varactor-based tunable frequency-selective rasorber (FSR) with embedded bias grid. The proposed structure consists of a lossy layer based on square-loop arrays and a ...
