Determination of the Element Currents

When all the mutual and the self-impedances of an assembly of stick arrays as shown in Fig. 3.8 has been determined, it is a relatively simple matter to find the currents on the elements. In fact, it was already discussed in my earlier book [62] and need therefore only to be restated here for easy reference. 

Let the stick arrays in Fig. 3.8 be exposed to an incident plane wave with direction of propagation equal to s. The voltages induced in the reference element of the three or more stick arrays are denoted y(2) yo) respectively. They are easily determined by application of (3.18). Similarly, the currents on each reference element are denoted by I and respectively. 

Then from the generalized Ohm s Law we obtain the following matrix equation
