Modeling of high-order (k-order) radioelements


A.V. Khokhlov – Dr. Sc. (Phys.-Math.), Professor, Department of Radiophysics and Nonlinear Dynamics, Saratov State University named after N.G. Chernyshevsky

High-order radioelements in which the voltage (current) is proportional to the second or higher derivative of the flowing current (voltage) are considered. It is shown that the parameters of the high-order radioelements have a multi-quadratic dependence on the frequency of an external influence. Resistive and jet (inductive or capacitor) high-order radioelements are proposed and realized in the form of electronic schemes containing k operational amplifiers and phasing RC-chains. The derived formula for calculating input resistances is experimentally confirmed by the measurement of frequency characteristics of the radioelements in the range of three octaves. The difference between the results does not exceed 1%. The high-order radioelements can be used in devices of pulse technique and automatic control to for regulate and compensate transition processes as well as to and also at create low-frequency resonant systems of enhanced Q factor.
