comprising plurality of mutually inclined plane surfaces, e.g. corner reflector

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Devices for reflection, refraction, diffraction or polarisation of waves radiated from an antenna, e.g. quasi-optical devices > Reflecting surfaces; Equivalent structures > comprising plurality of mutually inclined plane surfaces, e.g. corner reflector

CPC:

Devices for reflection, refraction, diffraction or polarisation of waves radiated from an antenna, e.g. quasi-optical devices (variable for purpose of altering directivity H01Q3/00; arrangements of such devices for guiding waves H01P3/20; variable for purpose of modulation H03C7/02) > Reflecting surfaces; Equivalent structures > comprising plurality of mutually inclined plane surfaces, e.g. corner reflector

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
