Ultraviolet Unblocked May 2026

A hemispherical fused silica concentrator with a narrow field-of-view (3°) that can be steered electronically. 4. Experimental Validation We constructed a UV² testbed in a suburban environment (humidity 65%, visibility 10 km). The transmitter and receiver were placed behind separate concrete barriers with no LOS.
