Gabor representations for hybrid antenna computations

This paper introduces the use of Gabor transforms to reflector antenna analysis, illustrating the topic with applications to the computation of field problems arising in the design of array-fed single and double reflector systems. The Gabor transform, and its discrete variant the Gabor series, have particularly attractive features since they exploit the localisation inherent in high-frequency fields scattered from large reflecting surfaces. Thus, a high-frequency field can be partitioned into regions which are essentially independent; each region can be modelled on a separate processor in a parallel cluster, with minimal inter-processor communication required for the calculation
