Design and characterization of a dielectric Q-plate for millimetre-wave photon orbital angular momentum applications
2012
We present the design, fabrication and beam pattern characterization of a nylon-
made q-plate that generates §2 charged OAM states at millimetre wavelengths. This q-plate
is optimized to work around 100 GHz but the same design can be scaled to work at other fre-
quencies in the millimetre-wave range. The simple manufacturing method used here allows a
cheap and fast q-plate production. The designed plate can create a point defect on the phase
front structure of a fundamental Gaussian beam with the associated optical vortex and annular
intensity pattern. The q-plate has been experimentally characterized using a millimetre-wave
Vector Network Analyzer and beam scanning test set-up.
