In this post I mention of the approach that would be taken to solve for the TE noise spectrum for a beam inside the substrate cavity.
Completing the same would be my plan for the next week.
In the COMSOL simulation, a gaussian pressure will be applied on both the flat surface of the cylinder. The strain would be calculated
using the Structural mechanics module and the temperature field would be calculated using the Heat Transfer module. The approach
is similar to that followed in Liu and Thorne. The Work dissipated would be calculated using the gradient of T. The spectral density is
then calculated using the FDT.
In the attachment, I have written briefly about the material I have studied this week along with my thoughts on the problem of the TE noise
