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 > Refracting or diffracting devices, e.g. lens, prism > formed of solid dielectric material
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) > Refracting or diffracting devices, e.g. lens, prism > formed of solid dielectric material
No child classifications to compare. This is a leaf node in both IPC and CPC.
