Abstract :
New time-domain sampling series for representing radiated fields on a plane in terms of plane-polar samples are presented. The representations make it possible for the advanced sampling field interpolations introduced in the frequency domain to be generalized to the time domain, thus enabling minimum redundance when using either a cardinal sampling scheme or a central interpolation one. Numerical analysis is then conducted to prove the effectiveness of the new representations
