Experiments in long-wavelength communication using modulated electron beam antennas: A parameter study

This preliminary study scopes the feasibility of producing electromagnetic signals from modulated beam antennas in the ionosphere and detecting those signals on the ground. Restricted to frequencies between tens of hertz and a megahertz, the report is essentially a handbook that gives predicted characteristics of the radiation produced by modulated electron beams employed in four different experiments. THe first is hypothetical and is optimized for the generation of detection of long-wavelength radiation. The other three are BERT-I, SEPAC, and VCAP.
