A Negative Permittivity Metamaterial Composed of Planar Resonators with Randomly Detuned Resonant Frequencies and Randomly Distributed in Space
Original language description
This paper investigates metamaterials composed of resonant particles with negative electric polarizability located in a 3D net. The main problem in fabricating of these materials is the spread of the resonant frequencies of particular planar resonators. This spread is caused by the tolerances of the fabrication process for planar resonators. Simulation shows that there is a limit to the dispersion of resonant frequencies that allow the metamaterial to behave as a metamaterial with negative effective permittivity. Two metamaterials with a negative real part of the effective permittivity were designed on the basis of simulations. The first metamaterial has a regular periodic structure. The second is a metamaterial in which the resonant particles are randomly distributed both in space and in orientation, and it offers an isotropic response. This metamaterial was fabricated by inserting planar resonators into plastic shells that can be poured into any volume and ensure random distribution of the resonant particles in space. The results of the simulations have been verified by measurements.
