Planar lensing lithography: enhancing the optical near field
, 2006
"... for my love Gemma In 2000, a controversial paper by John Pendry surmised that a slab of negative index material could act as a perfect lens, projecting images with resolution detail beyond the limits of conventional lensing systems. A thin silver slab was his realistic suggestion for a practical nea ..."

LEFT HANDED MATERIALS: A NEW PARADIGM IN STRUCTURED ELECTROMAGNETICS
, 2010
"... A new paradigm has emerged exhibiting reverse electromagnetic properties. Novel composite and micro-structured materials (metamaterials) have been designed to control electromagnetic radiation. Such substances have been called as Left Handed Material (LHM) with simultaneous negative permittivity and ..."

, to create lenses that are not diffraction limited, cloaking, sensors (chemical, biological and individual molecule), optical and radio communication. This new development in structured electromagnetic materials has had a dramatic impact on the physics, optics and engineering communities.

"... We present the experimental reconstruction of sub-wavelength features from the far-field of sparse optical objects. We show that it is sufficient to know that the object is sparse, and only that, and recover 100 nm features with the resolution of 30 nm, for an illuminating wavelength of =532 nm. Our ..."

502 PERSPECTIVES APPLIED PHYSICS
"... 1968, Veselago conceived of a material whose index of refraction, unlike that of any known material, could be negative (1). He suggested that this negative-index material would reverse nearly all known optical phenomena. Amid considerable initial skepticism, negative refraction was experimentally co ..."

was a speculation by Pendry (4) that a thin negative-index film should function as a “superlens, ” providing image detail with a resolution beyond the diffraction limit to which all positive-index lenses are subject. On page 534 of this issue, Fang et al. (5) confirm the theoretical predictions
The Department of Energy for a program of research entitled: MEASUREMENTS OF NANOSTRUCTURES WITH MICROMACHINED MICROSCOPES Principal Investigators: MEASUREMENTS OF NANOSTRUCTURES WITH MICROMACHINED MICROSCOPES
"... Summary Semiconductor devices, optical storage devices, and hard disks have minimum feature sizes that are becoming smaller and smaller. The minimum feature size in production devices is presently less than 130 nm, and far smaller devices are forecast for the future. As each generation of devices d ..."

decreases in size, it is often said that the familiar optical techniques employed for measurement and lithography will no longer be viable. However, the use of near-field principles-in which definition is no longer limited by diffraction-makes it possible to observe feature sizes considerably smaller than

"... Ultracold atoms in optical lattices provide a highly control-lable environment for the clean experimental realization of various model Hamiltonians from condensed matter and statistical physics. For example, the two-component Bose-Hubbard model, which re-duces to an anisotropic spin-1/2 Heisenberg m ..."

model in a certain limit and thus allows for the study of quantum magnetism, can be im-plemented by using bosons with two different internal states that couple differently to an optical lattice potential. In this thesis, I present our first experiments with two-component hyperfine-state mixtures
1FlatCam: Thin, Bare-Sensor Cameras using Coded Aperture and Computation
"... FlatCam is a thin form-factor lensless camera that consists of a coded mask placed on top of a bare, conventional sensor array. Unlike a traditional, lens-based camera where an image of the scene is directly recorded on the sensor pixels, each pixel in FlatCam records a linear combination of light f ..."
