Abstract:

A transformer can be constructed as a low frequency band pass filter by introducing a highly conductive and low permeability material between the primary and secondary windings of the transformer. Starting with Maxwells equations, and assuming first a sinusoidal input signal, the output voltage is obtained as a function of frequency, along with an expression for the frequency where the maximum voltage occurs. Then with a step input, the voltage and power output characteristics are given as a function of time. Experimental data is presented confirming the predictions of both cases. At the end of the report two simple systems are proposed as possible communication linking the aircraft and weapon one being a tuned circuit arrangement and the other a pulsing system. In both cases it is shown that RADAR will not affect the internal components of the weapon as long as the weapon is completely surrounded by a conducting shield.
