Gsn Raju Electromagnetic Field Theory 35.pdf


The mathematical model describing the electromagnetic phenomena in this study requires the use of the complete set of Maxwell equations; because at frequencies above about 400 MHz, the steady or quasi steady approximations fail. We have used the COMSOL RF Module Version 5.2. For high frequency models, voltage is not a well-defined variable and it is necessary to use scattering parameters (S), defined in terms of electric fields. Scattering parameters (or S-parameters) are complex, frequency dependent variables describing the transmission and reflection of electromagnetic waves at different ports of a device. S-parameters originate from transmission-line theory and are defined in terms of transmitted and reflected voltage waves.

The derivation that follows is typical to analysis of electromagnetic fields using scattering parameters [45]. The equivalent simple diagram of the radar head model is shown 1C. The diagram shows a voltage source feeding into the radar with a source impedance of Z0. If we define and as the square root of the forward and reflected incident electromagnetic waves, we can define the scattering function S11 as, [45], and the input impedance can be express as:(1)
