Quick start video
To calculate Epsilon-Mu microwave spectra enter required parameters and press the 'RUN!' button
Choose the type of your measurement cell:
Coaxial
Waveguide
For frequencies up to 18 GHz, 7/3.04 mm airline with N-type connectors is typically used.
Choose the type of your material:
Non-Magnetic
Magnetic
Non-magnetic material means that during calculation Mu=1 is assumed and only complex dielectric permittivity is calculated
Choose algorithm:
NRW
Iterative
NRW is faster, Iterative does not depend on Lpos
Enter the sample thickness
Ls
(in mm):
For example: 2.2
Enter
Lc
(in mm):
Length of airline cell (distance between calibration planes)
Enter
Lpos
(in mm):
Distance from Port 1 to the sample (required for NRW algorithm)
Enter the waveguide width
a
(in mm):
Enter the initial value of
Re(Eps)
at start frequency:
For typical plastics 10>Re(Eps)>2
Enter the initial value of
Im(Eps)
at start frequency:
For typical plastics Im(Eps)<0.5
Enter the initial value of
Re(Mu)
at start frequency:
For most materials 1
Enter the initial value of
Im(Mu)
at start frequency:
Usually Im(Mu)<0.5 for frequencies above 1 GHz
Upload S-parameters spectra
Please, add your .s2p file
