College of Optical Sciences News for April 26, 2007

 

Today:  Colloquium -- 3:30 p.m. -- Meinel 307

 

This concludes our 2006-2007 Colloquium series.  Colloquium will resume in the fall and we hope you will join us then.

 

Richard Ziolkowski of the University of Arizona will present Metamaterial-Enabled Resonant Electrically-Small Scattering and Radiating Systems in the Microwave and Optical Regimes.  Scott Tyo is the host.  Abstract:  There continues to be a great desire for high performance electrically small radiating and scattering systems from the microwave to the optical regimes whose physical characteristics and electromagnetic responses could be tailored to satisfy a wide range of applications.  Metamaterials, artificial materials whose electromagnetic responses can in principle be engineered to any negative or positive value, have been shown recently to be a potential enabling technology for these radiating and scattering systems.   Traditional electrically small radiating and scattering systems are poor transducers of their input or excitation energy. Several metamaterial-based configurations have been demonstrated recently that significantly improve the radiating and scattering performance characteristics of these systems.  The resulting systems are resonant despite being significantly sub-wavelength in size.  For instance, an electrically-small epsilon-negative (ENG) or double negative (DNG) spherical shell surrounding an electrically-small dipole antenna can be designed to act as an effective distributed inductor that is properly matched to the capacitive electric dipole element to form a naturally resonant LC structure, as well as to act as a resistive matching element to the source. Thus, an overall efficiency of 100% can be achieved in such an electrically-small radiating system.   The reciprocal configuration, plane wave scattering from an electrically-small ENG or DNG metamaterial-coated sphere, has been shown to exhibit unity scattering. Moreover, by introducing gain media, the effects of losses and dispersion can be controlled. For instance, lasing has been demonstrated at visible wavelengths in an electrically-small metal coated nano-particle.  A review of the progress to date on all of these resonant metamaterial-based electrically small radiating and scattering systems, and their potential practical microwave and optical realizations will be given. The effects of losses and dispersion will be emphasized in the discussion.

 

Today:  Special Presentation -- 2:00 p.m. -- Meinel 701

 

Vladimir P. Drachev, PhD, Senior Scientist at Birck Nanotechnology Center and School of Electrical and Computer Engineering Purdue University, will present Optical Plasmonic Metamaterials With Negative Refractive Index.  Nasser Peyghambarian is the host.  Abstract:  Refractive index is the most fundamental parameter to describe the interaction of electromagnetic radiation with matter. It is a complex number where real part has generally been considered to be positive. While negative refractive index does not violate any physical law, materials with negative index have some unusual and counterintuitive properties. For example, light refracted at an interface between positive and negative index materials is bent in the “wrong” way with respect the normal. In this case, the wave and Pointing vectors are anti-parallel, and three vectors, electric and magnetic fields, and wave vector form a left-handed system.  In this talk I will discuss our experimental realizations of negative index materials at telecommunication wavelength and near 800 nm. Our designs make use of localized plasmon resonant metal nanoparticles or nanoholes in metal films. The samples of a subwavelength bi-periodic cross-grating, consisting of two perforated thin metal layers separated by a thin dielectric show both a negative effective permeability and a negative effective permittivity for linearly polarized light with a wavelength between 799 and 818 nm, and the real part of its refractive index is about −1.0 at 813 nm. The ratio −Re(n)/Im(n) is close to 1.3 at 813 nm. For an orthogonal polarization, the same sample exhibits a negative refractive index at 772 nm.  Metamaterials with negative effective permeability across the whole visible range have been realized with sub-wavelength gratings of paired strips. We will discuss also the basic properties of metal nanostructures, including effect of surface roughness on the metal permittivity and effective parameters of metamaterials.

 

SpNext Week:  May 3, 2007 -- Special Seminar -- 2:00 p.m. -- Meinel 701

 

Takao Suzuki, Vice President of Toyota Technological Institute, will present High Magnetic Anisotropy Materials: From Bulk through Multilayers to Nano-scaled Particles.  Masud Mansuripur is the host.  Abstract:  "Magnetic anisotropy” is clearly one of the basic properties in magnetic substances. In particular, magneto-crystalline anisotropy is thought to be intrinsic for a given “bulk” material, but theoretical understandings of it are not satisfactory, as often demonstrated in many cases. In multilayers and nanoparticles where surface (interfacial) magnetic anisotropy plays a key role, magnetic behaviors are significantly influenced by extrinsic (induced) magnetic anisotropy.  Among many alloy systems, ordered alloys are known to exhibit high magnetic anisotropy, and in particular, the L1o ordered phase is of great interest because of bit-patterned magnetic data storage applications.  Nano-composite particles of high magnetic anisotropy phase, together with other magnetic anisotropy are also the subject of intensive research, since they offer potential for various applications, such as hybrid data storage, sensors and bio-devices.  The lecture is tutorially-oriented and addresses “Magnetism and structure of thin films and nano-composite particles of high magnetic anisotropy ordered phase. An in-depth review of magnetic anisotropy in representing materials is given, followed by recent developments of novel materials of high magnetic anisotropy. Recent developments on high magnetic anisotropy of novel multilayers and nano-composites will be presented. Emphasis is placed on “quasi-L12 structured alloy thin films of very high magnetic anisotropy and on (FePt/FeRh) nano-composites of the first order-transition type, in conjunction with possible applications.
