Microwave beaming distances

WebFor the target parameters of 10 W at 100 m distance, sufficiently powerful microwave sources exist at 2.45 GHz, but the process is so inefficient (<1% efficiency) due to spreading of the power beam that there is a large hazard area. A hazard free system for short range MPB could be developed at 2.45 GHz frequency with a 78-W transmitter. Web8 apr. 2024 · Powerful, radio-wavelength laser light has been detected emanating from the greatest distance across deep space yet. It's a type of massless cosmic object called a megamaser, and its light has traveled for a jaw-dropping 5 billion light-years to reach us here on Earth. The astronomers who discovered it using the MeerKAT radio telescope in …

Far field methods achieve longer ranges, often multiple kilometer ranges, where the distance is much greater than the diameter of the device(s). High-directivity antennas or well-collimated laser light produce a beam of energy that can be made to match the shape of the receiving area. The maximum directivity for antennas is physically limited by diffraction.
