Notes |
|
Propagation Speed |
Outputs the propagation speed.
The propagation speed c[m/s] calculated with relative permittivity ε and relative permeability μ as below.
c = (ε×μ)-0.5
|
|
Propagation Time |
Outputs the propagation time.
The propagation time is given by propagation distance divided by propagation speed. |
|
Wavelength |
Outputs the wavelength.
The wavelength is given by the propagation speed divided by frequency. |
