US 4,059,803 A · Method of converting the electromagnetic spectrum carrier frequency and an electromagnetic energy receiver for same

Abstract

A method of converting the carrier frequency of an incoming electromagnetic wave spectrum in an electromagnetic energy receiver comprising a converter, whereby the energy of the electromagnetic waves received by the receiver is accumulated in the input resonant system of the aforementioned converter which is frequency-selective and can be returned in the operating frequency range of this receiver. The electromagnetic energy is accumulated either directly in the material of the semiconductor, in particular, dielectric element used in the above input resonant system, or in a resonator which is contained in the same input resonant system and is built on sections of a lumped- and/or distributed-parameter line and which includes a semiconductor element. The electromagnetic characteristics of the semiconductor element depend on the electromagnetic parameters of constant and variable magnetic and electric fields acting upon this element. A periodic time change in the magnitude of the incoming electromagnetic energy accumulated in the input resonant system of the converter, i.e. auxiliary power modulation of the incoming electromagnetic waves, is brought about by selecting appropriate electromagnetic parameters of the constant and variable magnetic and electric fields acting upon the material of the aforementioned semiconductor element. An electromagnetic energy receiver comprising at least one converter and an output device connected in series. The converter is made in the form of an input resonant system and an output resonant system connected by means of a spatial detection system; the input resonant system comprises at least one semiconductor element and is tuned to the time-average value of the carrier frequency of the incoming electromagnetic waves, while the output resonant system is tuned to a frequency which is a multiple of the time-constant frequency of the auxiliary power modulation imposed on the incoming electromagnetic waves. The invention is intended for application mainly in the field of radio physics and electronics.
