I did something concerned with getting resonate frequency of
resonator using FDTD,the structure was very simple.But as
far
as I know,you just need to set up Yee's Grid in the
volume,and
use a pulse as excitation,do FDTD in the volume for a time
period long enough until the fields in the resonator get
stable,
then take the field at certain points as sample,do FFT,and
plot
it in frequency domain,you will see the resonate
frequency,which
is determined by the structure of the resonator. |
