In this paper we explain the linear sampling method and its performances under various scattering conditions by means of an analysis of the far-field equation based on the principle of energy conservation. Specifically, we consider the conservation of energy along the flow strips of the Poynting vector associated with the scattered field whose far-field pattern is one of the two terms in the far-field equation. The behavior of these flow lines is numerically investigated and theoretically… 
The Role of Point Sources and Their Power Fluxes in the Linear Sampling Method
TLDR
This paper analyzes how average power fluxes are carried throughout the host medium by the flow tubes of radiating fields, and shows that the far-field equation, which is the core of the linear sampling method, can be regarded as a physical constraint linking the power flux of the scattered wave with that of the field radiated by a point source.

In this article we propose a physical approach to the linear sampling method (LSM) for a possibly inhomogeneous and lossy background, whereby the modified far-field equation at the basis of the
A Parameter-Free Linear Sampling Method
TLDR
Free from a priori information pertaining to the geometry to be inspected, the upper and lower bounds of the profile of scatterers are pursued and the sensible frequency limit of the incident electromagnetic wave is estimated a posteriori.
