Energy Densities of Microwave Radiating Systems

W. E. TOLLES, W. J. HORVATH · 1956

This 1956 technical analysis examined power densities from early microwave radar and communication systems developed during World War II. The study found that while microwave systems don't necessarily generate more total power than older radio transmitters, they can concentrate electromagnetic energy into much smaller areas through high-gain antennas and waveguides. This concentration creates significantly higher power density exposures in localized areas around microwave equipment.
