Focusing system for laboratory experiment of millimeter wave induced bioeffects

A focusing system, consisting of horn antenna and lens, has been designed for the laboratory experiment of millimeter wave induced bioeffects. It adopts quasi-optical techniques, and can operate at 95 GHz and radiate GW-level power. For the millimeter wave source at W-level, the power density and area of its focal spot are 0.01～2 W·cm-2 and 0.8～30 cm2, respectively. In addition, the system has been applied successfully to the laboratory experiment of millimeter wave induced bioeffects.
