WebIn this paper, the question of how to efficiently sample the field radiated by a circumference arc source is addressed. Classical sampling strategies require the acquisition of a redundant number of field measurements that can make the acquisition time prohibitive. For such reason, the paper aims at finding the minimum number of basis functions representing … Webfunctions on an interval. A basis for bandlimited functions, the prolate spheroidal wave functions (PSWFs), was introduced in the 1960s by Slepian et al. in a series of papers [1–5]. Recently the generalized Gaussian quadratures became available in [6,7], making it possible to construct efficient numerical algorithms for such functions.
