Abstract The design of antennas for terahertz systems remains a significant challenge. These antennas must provide very high gain to overcome significant free-space path loss, which limits their ability to broadcast or receive a beam over a wide angu

Despite the rapidly growing interest in exploiting millimeter and terahertz waves for wireless data transfer, the role of reflected non-line-of-sight (NLOS) paths in wireless networking is one of the least explored questions. In this paper, we invest

The applications of terahertz (THz) wireless communication require studies on link performance in all kinds of atmospheric conditions, including rain, fog, cloud, haze, and snow. Here, we present theoretical investigations on THz wave propagation in
