High-Throughput and Low-Cost Terahertz All-Dielectric Resonators Made of Polymer/Ceramic Composite Particles
Udgivet 2019-01-01Få fuldtekstIn this paper, we report a new and generic method for all-dielectric resonators operating at terahertz (THz) frequencies based on polymer/ceramic composite particles. In this method, the polymer solution is added into ceramic powders (strontium titanate) and prilling technology is employed to make t...

Generation of Orbital Angular Momentum Beam With Circular Polarization Ceramic Antenna Array
Udgivet 2019-01-01Få fuldtekstOrbital angular momentum (OAM) beams can be generated at many microwave frequencies by using antenna array. However, the complexity of the system and inability to transmit over long distances limit the applications of OAM beams in the radio domain. Here, a significantly simplified global positioning...
