The complex-source (CS) method in conjunction with the spherical-multipole analysis is used to explore and demonstrate the different local phenomena associated with beam-wave scattering by acoustically hard or soft circular cones. The illumination by

This two-part article is concerned with the medium reconstruction using the beam-based tomographic inverse scattering. This Part II is based on the results of Part I that has dealt with the preprocessing phase. Specifically, we defined there the beam

We derive a new asymptotic procedure for the analysis of scalar wave diffraction by semi-infinite circular cones and apply it to derive a new closed-form expression for the tip-diffracted field in the wide-angle limit. The wide-angle cone is importan

We review the progress of the BS approach, starting from the original Greens function formulations in the frequency and time domains; the Gabor-series formulations for aperture-source distributions; the UWB phase-space formulations; and up to the bea

We present two novel beam-summation schemes for radiation from time-harmonic or time-dependent volume source distributions, where the field is expanded using a discrete phase-space set of beam-wave propagators. The generic term “beams” is used he

In this chapter, the authors present a beam-based local diffraction-tomography (DT) inversion scheme as an alternative to the conventional Green's function or plane-wave inversion schemes. The beam waves are used here as basis functions for local pha

In Part I of this two-part sequence, we introduced a novel beam summation (BS) scheme for tracking waves through fluctuating media. A key step has been the proof that the set of beam propagators constitutes a frame everywhere in the propagation domai

We present a novel beam summation (BS) formulation for tracking wavefields in fluctuating media. This formulation utilizes the ultrawideband phase-space BS method, which is structured upon a windowed Fourier transform (WFT) frame expansion of the sou
