Rotman Lens-Based Circular Array for Generating Five-mode OAM Radio Beams
Recently, vortex beam carrying orbital angular momentum (OAM) for radio communications has attracted much attention for its potential of transmitting multiple signals simultaneously at the same frequency, which can be used to increase the channel capacity. However, most of the methods for getting multi-mode OAM radio beams remain up to now mainly at simulation level, since their implementations...
متن کاملSlowing light with Fabry–Perot resonator arrays
We analyze the transmission of light through coupled-resonator optical waveguides in the form of evanescently coupled Fabry–Perot resonator arrays. We develop a transfer matrix method to calculate the amplitude and phase responses of the arrays. We also discuss the inclusion of optical gain in the system to compensate for losses in these structures. Owing to the compact length along the propaga...

Recently, vortex beam carrying orbital angular momentum (OAM) for radio communications has attracted much attention for its potential of transmitting multiple signals simultaneously at the same frequency, which can be used to increase the channel capacity. However, most of the methods for getting multi-mode OAM radio beams are of complicated structure and very high cost. This paper provides an ...
متن کاملDielectric Rotman Lens Alternatives for Broadband Multiple Beam Antennas in Multi-function Rf Applications
The U.S. Army Research Laboratory (ARL) is currently pursuing key technologies for the integration of a low-cost communications and radar system that allows performing multiple functionalities with a single system and an antenna. These radar and communication functions include target acquisition, combat identification, weapons guidance, secure point-to-point communications, active protection, n...
متن کاملDesign Method for Circularly Polarized Fabry-Perot Cavity Antennas
A new class of circularly polarized (CP) Fabry-Perot cavity antennas is introduced that maintain the simplicity of a linearly polarized primary feed and a single cavity structure. The proposed antennas employ a double-sided partially reflective surface (PRS), which allows independent control of the magnitude and phase responses for the reflection and transmission coefficients. In conjunction wi...
