Geometric Phase in Phasing of Antenna Arrays [PDF]
Symposium - International Astronomical Union, 2002 The response of a pair of differently polarized antennas is determined by their polarization states and a phase between them which has a geometric part which becomes discontinuous at singular points in the parameter space. Some consequences are described.
