Standard Waveguide Bands

Frequency Objects

These are predefined Frequency objects that correspond to standard waveguide bands. This information is taken from the VDI Application Note 1002 [1] .

Object Name	Description
f_wr10	WR-10, 75-110 GHz
f_wr3	WR-3, 220-325 GHz
f_wr2p2	WR-2.2, 330-500 GHz
f_wr1p5	WR-1.5, 500-750 GHz
f_wr1	WR-1, 750-1100 GHz
...	...

RectangularWaveguide Objects

These are predefined RectangularWaveguide objects for standard waveguide bands.

Object Name	Description
wr10	WR-10, 75-110 GHz
wr3	WR-3, 220-325 GHz
wr2p2	WR-2.2, 330-500 GHz
wr1p5	WR-1.5, 500-750 GHz
wr1	WR-1, 750-1100 GHz
...	...

Shorthand Names

Below is a list of shorthand object names which can be use to save some typing. These names are defined in the main __init__ module.

Shorthand	Full Object Name
F	Frequency
N	Network
NS	NetworkSet
M	Media
C	Calibration

The following are shorthand names for commonly used, but unfortunately longwinded functions.

Shorthand	Full Object Name
saf	save_all_figs()
