Dielectric optical

The nonlinear optical and dielectric properties of polymers find increasing use in devices, such as cladding and coatings for optical fibres, piezoelectric and optical fibre sensors, frequency doublers, and thin films for integrated optics applications. It is therefore important to understand the dielectric, optical and mechanical response of polymeric materials to optimize their usage. The parameters that are important to evaluate these properties of polymers are their dipole moment polarizability a, hyperpolarizabilities 0...

This book is specifically addressed to the properties of polar oxides as well as to their chac-terization and imaging techniques. The dielectric, optic, piezoelectric, pyroelectric behavior of this class of materials is discussed. Emphasis is placed on novel methods in the field of electrical and optical investigations, scanning probe microcoscopy (spm) techniques and advanced X-ray analysis. The book starts with tutorial reviews, and arrives at up-to-date results about polar oxides. Therefore, it not only stimulates and further motivates young scientists but is of considerable interest for the members of our community.

The previous chapter dealt with how atoms form bonds with one another. This chapter is devoted to the next level of structure, namely, the arrangement of ions and atoms in crystalline ceramics. This topic is of vital importance because many properties, including thermal, electrical, dielectric, optical, and magnetic ones, are quite sensitive to crystal structures. 

The essential feature of dielectric optical film materials is their very low absorption (a < 103 cm 1) in the relevant region of the spectrum. The films are primarily characterized by transparency and refractive index. 

One may expect that, especially if the scale of phase separation could be extended at will, such preparative techniques may be useful in obtaining types of multicomponent polymeric systems which have unusual dielectric, optical, and mechanical properties. 

The spot diagram is a standard characterization of classical optical systems. This is also applied to dielectric optical waveguides and fibers as well as microoptic components. In Fig. 25, we show a typical spot diagram for a GI rod lens that exhibits some aberrations due to the index distribution. 

Recently, the investigation of polymer brushes has been focused on the synthesis of new tethered polymer systems primarily through surface-initiated polymerization (SIP). Previously, the term polymer brushes has been limited to the investigation of block copolymers (qv) or end-functional linear polymers that have been physically or chemically adsorbed to surfaces, respectively (3,4). Recent synthetic efforts using different polymerization mechanisms have resulted in the discovery of many novel properties of polymer brushes. This has been aided no less than the use of innovative and unique surface-sensitive analysis methods as applied to flat substrates and particles. The study of polymer brushes has benefited from improved dielectric, optical, spectroscopic, and microscopic characterization methods. Understanding the chemistry of these grafting reactions and how... 

The desired, in-use properties (i.e., mechanical, electrical, dielectric, optical, thermal, physical, and magnetic) of a ceramic are generally only realized after a dense, cohesive body is produced by thermal consolidation. The properties of a finished ceramic body are largely dependent on the degree of densification achieved and the microstructure produced during thermal consolidation consequently, thermal consolidation is one of the most critical steps in ceramic processing.

Note that the intensity of the evanescent wave in an atom mirror can be increased by two or three orders of magnitude on account of excitation of surface plasmons produced by introducing a thin metal layer into the dielectric-vacuum interface (Esslinger et al. 1993). Another method to intensify the evanescent wave is to introduce a dielectric film of high refractive index, which produces a dielectric optical fiber for the laser radiation. The repeated reflection of the laser light from the dielectric-vacuum and dielectric-dielectric interfaces substantially increases the intensity of the evanescent wave (Kaiser et al. 1994).
