Transformation Optics for Full-Wave Calculation of Microwave Applicators With Elements in Translation

The aim of this letter is to propose full-wave calculation of microwave (MW) applicators with elements in translation based on transformation optics. In the proposed 2-D model, the motion region is surrounded by two slabs with time-varying anisotropic homogenous media on the basis of transformation optics: one is to compress the electric field and the other is to stretch the electric field. Thus, the electric field of applicators with elements in translation can be equivalently calculated by full-wave analysis without any remeshing steps. It is helpful to model the heating process of food or biological package transportation on conveyor belts in industrial MW heating accurately and efficiently.
