Exercise 13

A waveguide is formed by two parallel copper sheets- c = 5.80 × 10 7 (S/m)- separated by a 5(cm) thick lossy dielectric- r = 2.25, r = 1, = 10 -10 (S/m). For an operating frequency of 10 (GHz), find , d , c , u p , u g , and g for
(a) the TEM mode,
(b) the TM 1 mode, and
(c) the TM 2 mode.
