Slots in the broad wall of a rectangular waveguide scatter power symmetrically, so that they can be modeled as a shunt admittance,Y, in a transmission line. Consider the waveguide structure below, with four equally space slots .68 lambda apart, where lamda is the wavelenght in the waveguide. slots 1 and 4 have normalized admittances y1/y0=y4/y0=.35 while slots 2 and 3 have normalized admittance y2/y0=y3/y0=.65 assume that there is zero electrical lenght between slot 1 and the absorber (match load).

draw a transmission line model for this device.

using smith chart determine the input admittance Yin and the SWR looking into the waveguide from the left at slot 4.
