Td. Drysdale et al., Variable polarisation compensator using artificial dielectrics for millimetre and submillimetre waves, ELECTR LETT, 37(3), 2001, pp. 149-150
A variable polarisation compensator has been designed and demonstrated expe
rimentally at 100GHz. The device uses two silicon plates with interlocking
artificial dielectric surfaces to produce a birefringence that varies with
the separation distance. The experimental results indicate a maximum differ
ential phase-shift of 74(degrees). and show good agreement with computer si
mulations.
