Experimental verification of metamaterial loaded small patch antennas
(Emerald Group Publishing Limited, 2013)
Purpose - Metamaterial unit cells composed of deep subwavelength resonators brought up new aspects to the antenna miniaturization problem. The paper experimentally demonstrates a metamaterial-inspired miniaturization method ...
Microwave transmission through metamaterials in free space
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 ...

The magical world of metamaterials
We review experimental and theoretical studies performed on left-handed metamaterials (LHM). The metamaterials exhibit quiet unusual electromagnetic properties such as negative refraction, negative phase velocity, subwavelength ...
Experimental study of subwavelength focusing by lefthanded metamaterials with a negative refractive index
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 ...
Transmission and reflection properties of composite double negative metamaterials in free space
We report free space transmission and the first reflection measurements of a composite double negative (DNG) metamaterial, also known as a left-handed material (LHM). The metaniaterial composes of the split-ring-resonators ...
Metamaterial based cloaking with sparse distribution of spiral resonators
We investigate the application of a metamaterial that is formed by the sparse distribution of spiral resonators as an optical transformation medium is in order to achieve electromagnetic cloaking. The well-known Clausius-Mossotti ...
Transmission properties of composite metamaterials in free space
(American Institute of Physics, 2002)
We propose and demonstrate a type of composite metamaterial which is constructed by combining thin copper wires and split ring resonators (SRRs) on the same board. The transmission measurements performed in free space ...
Development of left-handed composite materials and negative refracting photonic crystals with subwavelength focusing
We review the studies conducted in our group concerning electromagnetic properties of metamaterials and photonic crystals with negative effective index of refraction. In particular, we demonstate the true left handed ...
Experimental demonstration of negative refraction and subwavelength imaging by left-handed composite metamaterials
(Cambridge University Press, 2006)
We report a true left-handed (LH) behavior and focusing in a composite metamaterial consisting of periodically arranged split ring resonator (SRR) and wire structures. The magnetic resonance of the SRR structure is ...
