parallel-plate waveguide. [?par·?‚lel ¦plat ?wav‚gid] (electromagnetism) Pair of parallel conducting planes used for propagating uniform circularly cylindrical waves having their axes normal to the plane.
A waveguide is a structure that guides waves, such as electromagnetic waves or sound, with minimal loss of energy by restricting expansion to one dimension or two. There is a similar effect in water waves constrained within a canal, or guns that have barrels which restrict hot gas expansion to maximize energy transfer to
24 May 2017 This set of Microwave Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Parallel Plate Waveguide". 1. If the width of a parallel plate waveguide is 30 mm and the distance between the parallel pates is 5 mm, with an intrinsic impedance of 377?, then the d) Cannot be defined
µ, ?. Transverse Electric (TE) Modes. For a parallel-plate waveguide, the plates are infinite in the y-extent; we need to study the propagation in the z-direction.

The parallel plate waveguide is the simplest structure consisting of two parallel PEC plates. You have The fundamental mode of the parallel plate waveguide is a planar wave between the plates with the electric field perpendicular to the plates. Moreover, you have to define a single expansion in the Expansion dialog.
4. What is meant by dominant mode? What is the dominant mode for parallel plate waveguide? (Apr/May 2012, R8). The mode having the lowest cutoff frequency is called dominant mode. The dominant mode for parallel plate waveguide is TEM. 5. Write down the relationship between phase velocity and group velocity.
