A PointSource Method in Inverse Acoustic Scattering.
"... We present a pointsource method to solve inverse acoustic obstacle scattering problems. The pointsource method gives a new and explicit procedure how to compute from the far field pattern u 1 of a scattered field an approximation for the total acoustic field u near the unknown obstacle. The poin ..."

The Point Source Method for Inverse Scattering in the Time Domain
, 2006
"... Many recent inverse scattering techniques have been designed for single frequency scattered fields in the frequency domain. In practice, however, the data is collected in the time domain. Frequency domain inverse scattering algorithms obviously apply to timeharmonic scattering, or nearly timeharmo ..."

inverse scattering via Fourier transforms without recourse to the conventional limiting amplitude principle; secondly, we apply the analysis in the first part of this work toward the extension of a particular scattering technique, namely the point source method, to scattering from the requisite pulses
THE SOLUTION OF HEATED PUNCH PROBLEMS BY POINT SOURCE METHODS
"... AbstractA method is described for finding the contact pressures and surface displacements of a semiinfinite elastic solid, indented by a rigid, heated punch. The problem is reduced to an equivalent isothermal problem by finding the surface displacements due to temperature changes alone, making use ..."

of various properties of the point source solution, and superposing these on the initial profile of the solid. The analysis is greatly simplified if the system is axisymmetric or contains axisymmetric regions. The method is illustrated by an example.
A Time Domain Point Source Method for Inverse Scattering by Rough Surfaces
"... In this paper we propose a new method to determine the location and shape of an unbounded rough surface from measurements of scattered electromagnetic waves. The proposed method is based on the point source method of Potthast (IMA J.Appl.Math., 61:119140, 1998) for inverse scattering by bounded obs ..."

Simulation of MultipleStation Ground Motions Using Stochastic PointSource Method with Spatial Coherency and Correlation Characteristics
"... Abstract Existing algorithms, including the stochastic pointsource method, used to simulate synthetic groundmotion records are aimed at sampling records at a single station or records at multiple stations. The application of the algorithms may not adequately reproduce the observed coherency struct ..."

1 BASIC THEORY OF DISTRIBUTED POINT SOURCE METHOD (DPSM) AND ITS APPLICATION TO SOME SIMPLE PROBLEMS
"... In this chapter, the historical evolution of distributed point source method (DPSM) and its basic principles are presented. First, the magnetic field generated by a magnetic transducer/sensor in a free space is obtained. A Ushaped magnetic sensor with highpermeability core is first modeled (Placko ..."
