Abstract :
This paper presents a novel 2D uniplanar periodic structure. Effective permittivity is very high and could be tuned by the insertion of a large number of MEMS variable capacitor in the material. Electromagnetic properties of the periodic structure are simulated by an FDTD algorithm. A theoretical test bench has been realized in order to measure the experimental dispersion curve. This paper presents the method of realization and experimental results.
