Click to expand... "fast" takes less time while "discrete" takes longer. To have first impression, fast can be used. for more accuracy, discrete is used. Or it's better to use CST? why? Click to expand... For UWB, CST takes much less time. This is due to the fact that it uses time domain signal and then converts it to freqeuency domain signal. It does not do the calculations at different frequency points.

Click to expand... I really didn't understand, what thickness you refer to.
