HFSS Tutorial 2: Dispersion Diagram I - em: talk
We want to use HFSS to obtain a dispersion diagram for the first mode for a parallel plate waveguide. A dispersion diagram is a plot of propagation constant versus frequency; a …
Propagating a plane wave obliquely down the waveguide at an arbitrary angle θ from the z-axis, reflections at each wall can be constructed. After reflection from two opposite-facing walls, the …
Can any one explain in detail what is dispersion diagram & how …
A dispersion diagram is a plot of frequency (usually in radians per second) on the vertical axis, against wavenumber (usually in radians per metre) on the horizontal axis.
The dispersion diagram, which is a graph based on “frequency” vs. spatial phase variations of the predefined parameter of “phase”, could obtained by the following step by step process:
