Measuring the Surface Properties of a Novel 3-D Artificial Magnetic Material

A novel three dimensional artificial magnetic material structure named here as Tunable Multi Layer Multi Dielectric High Impedance Surface (TMMD-HIS) is proposed. These three dimensional structures have periodicity along all the three dimensions and the remarkable feature is that these systems have complete band gaps and therefore propagation states are not allowed in any direction. The measurement of its surface properties is a means to understand its transmission coefficient, reflection coefficient and surface wave band gap characteristics. For analysis, numerical technique of Finite Element Method is used. The results obtained in HFSS simulation software are presented.
