As a result of the ever growing number of functionalities and standards to be supported by communication systems, as well as the constant development of radar and imaging technologies, a key research area in the field of microwaves and millimeter waves is ...
We propose an artificial three-dimensional material that exhibits a strong resonance in the effective permeability in the visible spectral domain. This material may be implemented in a two-step procedure. First, a metamaterial made of densely packed metall ...
We perform rigorous simulations of hybrid long-range modes guided by a central metal core and a two-dimensional dielectric slab. We show that these modes are subject to fewer limitations than conventional long-range plasmon modes in terms of field confinem ...
The modeling and design of metamaterial composite right/left handed transmission lines (CRLH-TL) is usually based on the assumption that its unit cell is small in terms of the host TL wavelength (d 0). However, it was also shown that this assumption is not ...
We propose the combination of a planar optical resonator and a solid immersion lens for resonantly enhanced non-contact near-field lithography. Subwavelength small spots can be produced by exciting the Bessel modes of the resonator. (C) 2008 Optical Societ ...

We present a photonic meta-material with planar dielectric chiral structures on SU-8 realized using nanoimprint lithography (NIL). A Si template with chiral structure arrays was first fabricated by electron beam lithography (EBL) followed by reactive ion e ...
Utilizing the underlying physics of evanescent-wave amplification by a negative-refractive-index slab, it is shown that evanescent waves with specific spatial frequencies can also be amplified without any reflection simply by two dielectric planar waveguid ...
This paper presents the modeling and design of one-dimensional metamaterial phase shifters (MPSs) in monolithic-microwave integrated-circuit technology based on the composite right/left-handed transmission-line approach. From a theoretical point-of-view, w ...
We experimentally and theoretically study the controlled coupling between localized and delocalized surface plasmon modes supported by a multilayer metallic photonic crystal slab. The model system to visualize the interaction phenomena consists of a gold n ...
We apply the Ewald acceleration technique to the efficient evaluation of periodic Green's functions (GFs) for 3-D skewed lattices like those arising in electromagnetic/photonic band-gap (EBG/PBG) structures and metamaterials (MTMs). We develop the expressi ...
