The sideband field resonating in a marginally stable cavity with thermal deformation was calculated using FFT and modal model, and a large discrepancy was observed. This document explains the limitation of the use of modal model when the mode mismatch is not good.
Notes and Changes:
Result using Hankel Transform is added
