            Abstract : 
In this paper, the properties of cylindrical high-permittivity dielectric particles are studied. The refractive index is calculated with a parameter retrieval method and a Fourier transform method. It is shown that the periodic particles have low losses, while being non-resonant and broadband. Furthermore, the refractive index can be adjustable according to the dimensions of the particles. Application examples are also presented.
