It is noted that larger knife-edge diffraction loss [L.

Propagation through loss with the added diffraction loss is shown in Figs.
Moreover, some physical insights have been discussed on the origin of the diffraction loss in the TIR facets.
By dispersing the spectrum across the MEMS chip, discrete sections of the spectrum can be 'blocked' by diffracting light into higher orders, while others can be reflected with no diffraction loss.
Knife-edge diffraction loss is then determined from the homograph in Figure 4.
The formula for the relative diffraction loss in spectral power is already well known, and it is noted below.
For the radiation present at a given wavelength [lambda] the diffraction loss can be described in terms of a unit-less parameter, v = 2[pi][PSI]R/[lambda].
When radio-wave transmitting under urban microcell, diffraction loss is so much more than reflection loss generally that it is quite necessary to distinguish reflection and diffraction using the type weight of the ray.
