Assignment #6 1. A parallel-plate wave guide is constructed for operating in the TEM mode only over the frequency range 0 < f < 3 GHz. The dielectric constant between plates is ε r =2.1.Determine the maximum allowable plate separation distance. 2. A parallel-plate wave guide is formed by copper sheet ( σ c =5.8*10 7 S/m) separated by 5 cm dielectric ( r =2.25, µ r =1, =10 -10 S/m). For an operating frequency of 10 GHz find β , α d , c , v p , v g , λ g for TM 1 mode. 3. Two parallel plate wave guide are joined end-to-end as shown in the figure. Find the frequency at which TE 1 mode does not have any reflection at the wave guide junction at Z=0 Hint: Write the field for Z<0 and Z>0.Since there is no reflections at Z=0 mode field at wave guide-1 and wave guide-2 must satisfy the boundary condition i.e. tangential component of E and normal component of H at junction must be continuous 4. Write the instantaneous field expression for the TE 1 mode in a parallel plate waveguide (taking it to be infinitely long in y direction and assuming wave
