Compact electromagnetic-radiation antenna

摘要

A compact random media size antenna employing random magnetic and dielectrics nm to mm range size particles in polymer hosts is used to transfer E & M oscillations in 1 kHz to 900 Mhz range using a 1 cm to 1 meter length antenna. This is achieved by using small size particles and a random mean path length of E & M wavefront travel in and about a core tube of effective length matching Leff=L2/2ltr, equivalent to λ/2 for transmitting and receiving E & M radiation, where L is the physical size of the antenna, ltris the transport scattering random walk length between particles and λ is the frequency wavelength.

1. A compact electromagnetic EM radiation antenna comprising an elongated core having a physical length L forming a host medium for magnetic-dielectric particles, said particle sizes being selected to be within the range of approximately 1 nm to 1 μm; an electrically conducting coil wound around said core and having terminals suitable for connection to a source of electrical energy; and magnetic-dielectric particles dispersed within said core host medium for scattering the EM radiation by said magnetic-dielectric particles to produce an average transport scattering walk length ltr, the effective length of the antenna being Leff=L2/2ltr=λ/2.
