頻譜 (Spectrum) : Analysis the spectrum
場圖(Field Pattern) : Analysis the field pattern。
To calculate : Radar-Cross-Section, Extinction-Scattering-Absorption
The incident mode profile : plane wave
To calculate :Transmission-Reflection
The incident mode profile : plane wave, Gaussian beam, Customize
Point Source or other shape
Point Source or other shape
Electric field (E), magnetic field (H), Voltage (V), Current (I)
(Probe fields are using Fast Fourier Transform, FFT)
voltage source, current source, Resistor, Inductance , Capacitor, Wire, Load Wire (*.stl)
Load Wire (*.stl)
If the layer thickness (ex. FR-4 PCB, copper layer) is much less than resolution delta (dx)
(Structure thickness << dx)
Then use the Load Wire method, can tune the resolution order to get the better structure
(Even doesn't use probe field or lumped element, also need to press this button to create void grids )
Start : Start Wavelength of observation (equal to end frequency)
End : End Wavelength of observation (equal to start frequency)
Center : center wavelength, use for modulate wave, the range between start and end.
Pulse : Input a pulse wave, obtain the scattering/absorption/extinction or transmission/reflection spectrum.
CW : Input a continue wave, obtain the field pattern.
Increment: (means how many numbers of wavelength will do the Fourier transform)
This is use for pulse wave, the increment number mean how much point will observe between the start and end wavelength (frequency) .
If the result of spectrum is analysis in wavelength, then checked the wavelength, if frequency, then checked the frequency.
checked the wavelength= Start + (End - Start)/(increment-1)*x |x=1~(increment-1)
checked the frequency= 1/End + (1/Start - 1/End)/(increment-1)*x |x=1~(increment-1)
