Title: ELECTROMAGNETIC TRANSMISSION LINE WAVE AMPLIFIER
Abstract:
An electromagnetic transmission line wave amplifier includes a transmission line and a parasitic dipole. The transmission line carries an electromagnetic transmission having an electric field, a magnetic field, a forward wave at a first wavelength and at a first frequency; and a backward wave. The parasitic dipole includes a pair of equal and oppositely charged or magnetized poles separated by a distance of less than about half of the first wavelength of the electromagnetic transmission. The parasitic dipole is formed with an inductive coil about equidistant from the poles to have a resonant frequency greater than the first frequency of the electromagnetic transmission and optimized for absorption of the forward wave at the first frequency. The parasitic dipole is further configured to emit an amplified electromagnetic wave in the transmission line when placed within the electric field or the magnetic field created by the electromagnetic transmission.
