log_psd
This function takes the n time domain samples (real or complex)
and finds the psd by taking (fft/n)^2. The two sided spectrum is
produced by shifting the psd The array freq provides the appropriate
frequency values for plotting purposes.
By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db
are set equal to -60db

FDTD_interface
FDTD仿真，空气和玻璃界面的折射现象，可以观察到电磁波的折射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor. )
