My research interests have revolved around Metamaterials, and their applications in the field of Electromagnetics, and Photonics. In recent years, the extraordinary electrical and magnetic properties provided by metamaterials have opened up new opportunities for novel applications including efficient solar cells, miniaturization of devices such as antennas and waveguides, novel devices for medical imaging especially magnetic resonance imaging, cloaking, and perfect lenses to name a few.

Natural materials own their electromagnetic properties to atoms, and molecules from which they are composed. On the other hand, metamaterials are engineered structures, in which inclusions smaller than a wavelength replace the role of atoms and molecules of a conventional material in defining electromagnetic properties. Therefore; metamaterials can be designed to achieve desirable electromagnetic properties at different frequency ranges, which provides added flexibility in the design of microwave, and optical devices.

In addition metamaterials provide extraordinary electromagnetic properties with negative refractive index as the most popular one. The refractive index is a measure of how much the speed of light, or waves in general, is reduced inside the medium. When waves crosses the interface between air, and a metamaterial with negative refractive index, the rays are bended in such a way that the rays that normally diverges in a positive medium, converge in a negative medium. This phenomenon that can’t be observed in natural materials opens up new opportunities in design of optical, and microwave devices.
