Note that the conduction loss of TEon decreases without limit as f ~ 00. An example of the conduction loss in a typical air-filled circular brass waveguide is shown in Fig. 25. 17. References D.

(a) Side view. (b) Top view. incident plane wave described in (22). The plane wave propagates in the direction k = ki , where ki = k( i sin 00 cos CPo + ysin 00 sin CPo + i cos ( 0 ) (93) The problem at hand is to find a field representation for the scattered field in the unbounded space (outside of the periodic slab).

The (total) gain G(k) in (60) is the sum of partial gains for any two orthogonal polarizations: G(k) = g(k, u) + g(k, v) which follows from (58). Peak Gains All of the six gains depend on the observation direction k = «(J, f/J). In applications we often use the maximum of a gain as a function of k. Thus, corresponding to (60), we define a peak gain for all polarizations by G = max G(k) = ~max IA(kW n (65) Basics 1-27 In a similar manner we define a peak gain for a specific polarization u. When a gain is given without a specified observation direction, it is customarily assumed to be the peak gain.
