We shall study the TM modes and the modes of a circular waveguide in this lecture. For dominant mode TE10, m=1, n=0 and hence, λ c = 2 7. The propagation mode of TE and TM in the rectangular waveguide depends on critical / cutoff method used.
In a rectangular waveguide, equation (3) gives the cut-off frequency for TE mn mode and TM mn mode. The reduced wave equation is given below.

If you think we've made any errors or omissions, get in touch. This list is our attempt at keeping a catalogue of other acoustics software we've either used, heard about, or found referenced on the web. However, this doesn't mean it's the best tool for every purpose! There is a diverse range of other acoustics-related software available, both commercially and open-source. The k-Wave toolbox is a powerful tool for general acoustic modelling.
