Radius 2λ and Increased Permittivity Using the Born Approximation, and Processing
Sources Independently and Recombining in Image Space, and Cepstrum Space

Note: Thirty-six sources are used with varying numbers of receivers equally and randomly spaced to show the
effects of aliasing and anti-aliasing techniques.
