  • Based on transformation-optical approach, the distribution of permittivity and permeability for the N-sided regular polygonal electromagnetic wave concentrator is derived and functionality of the concentrator is numerically confirmed by the finite element solver COMSOL. Electric field and total energy distributions in the vicinity of the three-, four-, five- and six-sided regular polygonal concentrators are simulated. The influence of the focus area and deviation of material parameters from perfect N-sided regular polygonal concentrator on the concentrating effect is studied. The results show that the smaller the focus area, the stronger the total energy density; The deviation of material parameters from perfect concentrator results in a distortion of the electrical field and total energy density distribution.
