Near-field subsurface electromagnetic tomography and holography
Methods of multifrequency tomography and holography of subsurface dielectric inhomogeneities in the near-field zone based on the solution of inverse scattering problem are studied from the viewpoint of their applicability for targets with strong dielectric contrasts or with a complicated internal structure. Results based on numerical simulation with input data calculated from Maxwell equations are presented.
Polarimetric Signature CNN based Complex Permittivity Estimation for Microwave Non-destructive Testing
Here, we present complex relative permittivity estimation algorithm using fully polarimetric data based convolutional neural network (CNN) approach for microwave nondestructive testing scenario. The three-dimensional FDTD simulation show that our method accurately retains both dielectric constant and conductivity of floor slab buried in concrete media.
A concept of general monotonicity and applications
In this paper we investigate properties of the general monotone sequences and functions, a generalization of monotone sequences and functions as well as of those of bounded variation. Some applications to various problems of analysis are given. © 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
