The possibility of recovery of the complex values of the plane wave reflection coefficient from plane-layered environment from the signal measured values at the output of the quadratic detector is shown . A new mathematical sensors model was proposed for diagnostics of metal surfaces, which is based on the full electrodynamic analysis of biconical scatterers and the sphere - conical resonators. A method for numerical modeling of rectangular thin dielectric inclusions with H-polarized electromagnetic wave, which is based on the solution of the loaded integral equation with logarithmic singularity was proposed. The principles of construction of a new class ECPT flaw based on the proposed concept of forming a feedback on current was developed. The analytical expression was obtained for the generalized control parameter, which in the linear approximation allows to calculate the overhead voltage of eddy current transducers taking into account the influence of constant magnetized field.
