Wireless communications in the low terahertz band (0.1 THz-1 THz) is a promising candidate to enable ultra-high-rate vehicular networks beyond 5G. The successful design and adoption of such systems require deep understanding THz channel specifics complex scenarios. In this paper, comprehensive measurement campaign reported with aim analyzing wave propagation at 300 GHz typical deployments. Foll...

Abstract Avalanche Photodiodes (APDs) are key semiconductor components that amplify weak optical signals via the impact ionization process, but this process’ stochastic nature introduces ‘excess’ noise, limiting useful signal to noise ratio (or sensitivity) is practically achievable. The APD material’s electron and hole coefficients ( α β respectively) critical parameters in regard, with very d...
