Sets of PIN diode-loaded unit cells are addressed column-wise to realise azimuthal elec- tromagnetic transformation capabilities with a simple, vialess feeding mechanism. Simulated results utilising manufacturer’s component data suggest a desirable average reflection loss of 1 dB. A particle swarm optimisation algorithm is employed to re- alise reflection phase uniformity. Oblique incidence performance is investigated, revealing desirable phase shift resolution versus incidence angle beyond 40 degrees for TM-polarised waves.
