In this paper, we present a novel beamforming algorithm that is designed for spherical microphone arrays and formulated in the spherical harmonic domain. The proposed algorithm employs sparse recovery, a compressed sensing technique, and assumes the position of the source signals are unknown. A forma...

The radiation efficiency, defined as the radiated power into free space to the incident power of the antenna, can be calculated by η=GD64. The measured realized gain G of the 1-D universal metasurface antenna is 9.3 dBi at 23.5 GHz based on the gain-comparison method, which uses a ...
of the electrons. By comparison, it can be said that when a photon is traveling long distance, the transmission is very easy, simpler, faster and much efficient than electrons transmission. Sometimes, at the time of turning on, photons may face some difficulty, so it is then converted into...

The purpose of this article is to draw a comparison between a traditional sub-6 GHz macrocellular and a mmWave base station radio and antenna design. It further covers how these design differences impact DPD implementation in mmWave arrays relative to sub-6 GHz radios. ...
Comparison of characteristics of different types of terahertz phase modulators. Generally, the current terahertz phase modulator still has the problems of small phase modulation range, large loss and high power consumption. Fortunately, a lot of excellent work is overcoming the above-mentioned problems....
