Modern wireless communication systems prefer higher frequencies to meet the growing demand for faster data transfer. The 300-GHz band, which lies near the lower end of the terahertz range, is a promising candidate for future sixth-generation (6G) wireless systems because it can support very high data rates and minimize atmospheric attenuation. However, using such high frequencies comes with major engineering challenges. Radio waves in this range suffer from severe free space path loss (FSPL), making signal transmission challenging over practical distances.
