We report free space, microwave measurements with varying incidence angle on a material that exhibits a negative index of refraction. The experiments measure the index of refraction directly, for normal incidence, on prisms with three different apex

This research encompassed the study of radio frequency (RF) and optical metamaterials. The RF study of metamaterials focuses on the polarization behavior of split-ring-resonators (SRR), wire-post (WP) elements, and the spatially dispersive behavior o

We have performed CW measurements on the metamaterial wedge providing detailed insight into its behavior and operating bandwidth limitations. Measurements with a narrowband modulated signal have demonstrated that negative refraction exists with a pra

The phenomenon of negative refraction in a Metamaterial wedge is known to be relatively narrowband. Here, we first experimentally estimate the negative refraction bandwidth of a Metamaterial wedge using a slab and a series of CW measurements. We subs

Our work here investigates the combination of similar broadside coupled rings (BCRs) with negative permittivity posts in a metamaterial prism, rather than the previous guided-wave medium. Free space measurement of negative refraction through a prism

Free space microwave measurements are reported for a split ring and post type metamaterial which exhibits negative refraction in a frequency band between 13.5 and 14.5 GHz. Varying azimuthal angles and magnitudes are achieved by changing the polariza

Materials with simultaneously negative electric permittivity and magnetic permeability are referred to as left handed, and are also called backward wave and double negative media. The first experimental demonstration of such a metamaterial combined m

We have started to investigate the fundamental electromagnetic properties of left-handed mesostructures in order to establish a basic understanding of their electromagnetic properties. Simulations have been performed on left-handed structures using A
