Geometric method for determining the phase shift in the ref ection of an electromagnetic wave from a conformal metasurface of a sensing element

Abstract

The current research of high-impedance conformal surfaces on metamaterials and multifunctional measuring devices based on them makes the task of determining their parameters and characteristics urgent. In this article, a geometric method for determining the phase shift in the in-phase refl ection of an electromagnetic wave from the conformal meta-surface of a sensitive element is developed and proposed. It is shown, that as a result, of the meta-surface bending the incident electromagnetic wave passes an additional path at a certain electrical length, which leads to an increase in the phase shift of the refl ected wave. Using the CST Studio Suite numerical simulation program, the values of the phase shift of incident and refl ected waves for planar and curved metasurfaces of sensitive elements of various topologies with radii of curvature of 40; 50; 60 mm are obtained. The results obtained were compared with analytical calculations, which showed a good correspondence. The proposed method can be used to calculate and simulate measuring transducers containing sensitive elements on high-impedance conformal meta-surfaces.
