However, there are apprehensions that if a power-beaming device can convert solar energy into a microwave beam and direct that beam at a specific point, one has to ask if the concept could be applied to a space-based weapon as well. Some devices are described as microwave weapons; the microwave range is commonly defined as being between 300 MHz and 300 GHz (wavelengths of 1 meter to 1 millimeter), which is within the radiofrequency (RF) range. Some examples of weapons which have been publicized by the military are as follows: Active Denial System is a millimeter wave source that heats the water in a hu… st anthony woodworks
