DIFF Subgroup
H01P 1/16

for mode selection, e.g. mode suppression or mode promotion; for mode conversion

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Auxiliary devices > for mode selection, e.g. mode suppression or mode promotion; for mode conversion

CPC:

Auxiliary devices (coupling devices of the waveguide type H01P5/00) > for mode selection, e.g. mode suppression or mode promotion; for mode conversion

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1980.
