We find: vg = (∂k ( m, n) z ∂ω) − 1 = vpu√1 − (fmn / f)2 which is always less than vpu for a propagating mode. Note that group velocity in the waveguide depends on frequency in two ways.

WebThe only way for the condition in [10] to be true for all values of x and z whenever y=b, we must have: If this is to be true everywhere, c3 could be zero. However, if c3 is zero (and we have already determined that c4 is zero), then all of the fields would end up being zero, because the function Y (y) in [7] would be zero everywhere. Webdimensions) and travels in the z-direction. For example, the cross-section of a rectangular waveguide is shown below. Unfortunately, the exact modes of such 2D waveguides are not as easy to complete as those of slab waveguide. The modes are neither TE nor TM. All modes have a small component of E and H fields in the direction of propagation. The E

A waveguide that can support only one mode. Note: Because different wavelengths constitute different modes and the number of modes is also dependent on the numerical aperture (NA) and the core diameter, a given multimode waveguide might support only one mode in a given wavelength range and therefore could be called a single-mode …
