The study on the properties of terahertz THz wave propagation in complex atmosphere always been key technology for variety terahertz communication modes, such aswideband and high-speed network, astro-satellite communication, altitude aero-craft communication, long distance vast data transfer, short range wireless security ommunication etc. There are four main factors make effects on the free space THz wave propagation attenuation, free space radiation loss, atmospheric gases loss, atmospheric particle scatter loss, material penetration attenuation, and quasi-multipath refraction loss effect. Among aforementioned factors, the first part free space radiation loss could be calculated by furies equation. The second part atmospheric gases loss is determined by wave frequency, weather condition and atmosphere composition. The third part atmospheric particle scatter could be neglected when compare with first two attenuation. While the fourth part material penetration attenuation is influenced by shield materials equivalent dielectric constant and its dimension. This paper discuses solid electronics based THz band TR modules design, and the series 0.34THz wave material penetration attenuation experiments diagram and its results.
