I'm studying the phenemenon of band gaps in a experiment, however the stop bands are proving hard to define using just a transmission spectrum dervived from the fft alogrithm.
I've heard that it may be possible to define the band region by plotting the dispersion relation of sound waves the...
Hello, I was wondering if someone more knowledgeable in loop-quantum gravity or string theory could discuss a bit about the following topic for me:
If there is a lower size limit (or length itself is quantized), does this (or can this) mean that there would be a dispersion relation for light...
Dispersion relations have the tendency to confuse me.
In general, I know what dispersion is, but trying to apply it to crystals, I just "can't see the forest among all those trees". :rolleyes:
In phonon dispersion, acoustical and optical phonons have quite a different dispersion behaviour...
