The issue of conditions for the excitation of thin disk resonators suspended in free space, to our knowledge, has not been addressed in the literature, though form-factor dependencies of excitation spectra (form-factor is the ratio of disk radius R to thickness L) have been investigated when the excitation occurs [2].
