Abstract

An internally powered electromagnetic signal transmitter is described in which defined magnetic fields direct beta radioisotope electrons to induce gigahertz oscillations in resonant cavities. The device resonant cavities can be fabricated from light weight metalized plastic materials to greatly decrease its weight compared to conventional gigahertz sources. The transmitter output power, frequencies, and longevity are a function of the magnetic field strength, radioisotope quantity, half-life, and decay energy. Embodiments of the disclosed devices can transmit frequencies in the S and Ka bands.
