The method would help researchers build high-resolution optical sensors and lenses,
They succeeded in developing a method to address the issue. They proposed using approximate boundary conditions instead of using boundary condition for tangential component of magnetic field, which made possible inverse Fourier expansion of surface conductivity function.
A periodic array of graphene ribbons could find applications in developing different optical devices such as optical sensors, light absorbent, lenses with super-resolution beyond the diffraction limit and terahertz metamaterials.
