The region between a pair of parallel perfectly conducting planes of infinite extent in the y and z directions is partially filled with a dielectric as shown in Figure. A 30 GHz $$T{E_{10}}$$ wave is incident on the air dielectric interface as shown. Find the VSWR at the interface.

For small signal a.c. operation, a practical forward biased diode can be modeled as

The static characteristic of an adequately forward biased p-n junction is a straight line, if the plot is of

The eigen values of the matrix $$A = \left[ {\matrix{ 0 & 1 \cr 1 & 0 \cr } } \right]$$ are
