Electromagnetic inverse scattering aims to reconstruct the distribution of the dielectric characteristics of unknown inhomogeneous dielectric object by scattering wave.

Objective To study the application of the linear sampling method(LSM) in 2D electromagnetic inverse scattering imaging and to mainly discuss the imaging quality of LSM with partial-view data.

Phase retrieval in EM inverse scattering from phaseless data;

The application of magnetic technologies, such as magnetic electrolysis, magnetic separation and magnetic agglomeration, in industrial wastewater treatment are introduced, and their principals and recent research situation,as well as their merits and demerits,and their development prospects are also described.
