Designing materials with desired electromagnetic properties
(Wiley, 2006)In this work, we suggest and demonstrate a robust method to tune the plasma frequencies of wire mediums. The method we suggest involves the use of two or more wire arrangements in the unit cell. By incorporating the method ... -
Electromagnetically induced left-handedness in a dense gas of three-level atoms
(The American Physical Society, 2004)Ways in which a three-level system can be used to change the frequency-dependent magnetic permeability of an atomic gas were discussed. The resulting macroscopic electrodynamics was also discussed. The two levels were ... -
Experimental study of subwavelength focusing by lefthanded metamaterials with a negative refractive index
(2007)Two dimensional (2D) left-handed metamaterials (LHM) exhibiting negative refraction and subwavelength imaging are studied experimentally. A left-handed transmission band is observed at the frequencies where both dielectric ... -
The magical world of metamaterials
(2009)In recent years, there has been a burgeoning interest in rapidly growing field of metamaterials due to their unprecedented properties unattainable from ordinary materials. Veselago pointed out that a material exhibiting ... -
Microwave transmission through metamaterials in free space
(2002)To investigate properties of metamaterials, composite structures which consists of periodical arrangement of thin copper wires and SRRs on a circuit board was constructed. Through this, the transmission properties of ... -
Negative refraction and subwavelength focusing using left-handed composite metamaterials
(2008)We review experimental studies performed on left-handed metamaterials (LHM) at microwave frequencies. The metamaterial structure is composed of periodic arrays of split-ring resonators and wire meshes and exhibits a ... -
Transmission and reflection properties of composite metamaterials in free space
(Optical Society of American (OSA), 2003)We measured transmission and reflection from SRRs, thin wires, and composite metamaterials in free space. X-band measurement exhibits high transmission magnitude for frequencies where both SRR and wire have effective ...
