During the demonstration, the US Naval Research Laboratory (NRL) transmitted 1.6 kW of energy per kilometer using a microwave beam at the US Army research site in Maryland.

The principle of operation is quite simple. The electricity is converted into microwaves, which are then focused on the receiver into an intense beam called rectal elements. These are very simple components consisting of an x-band field antenna with a radio frequency diode. When microwaves hit the rectum, the elements produce direct current.

Despite initial doubts, the microwave was surprisingly effective, and the NRL team, led by Advanced Concepts Group president Christopher Rodenbeck, was commissioned by the Department of Defense to develop the Safe and Continuous Power Radiation – Microwave (SCOPE-M) project. to discover this technology.

Using a 10 GHz microwave beam, the SCOPE-M was installed in two locations. The first is at the US Army Research Field in Blossom Point, Maryland, and the second is at the Haystack Ultra Wideband Satellite Imaging Radar at the Massachusetts Institute of Technology. This frequency was chosen not only because it can transmit signals even in heavy rain with less than five percent power loss, but also because it is safe for use in environments with birds, animals and people in accordance with international standards.
