CONTENTS 1 Electromagnetic Radiation

But the unadorned Eqs. (9.1.5) and (9.1.6) do not make sufficiently clear the physical significance of the nonstationary,initially-localized, f (O) states that are most easily created by a short, Fourier transform limited pulse of electromagnetic radiation. Short is not an absolute quality. For a sufficiently short pulse, the nature of the initial localization prepared and the specific dynamical processes sampled depend primarily on the duration of the preparation pulse and secondarily on its spectral content (Heller, et ai, 1982 Johnson, et ai, 1996). 

Although a simple Fourier transform relationship can exist between a high spectral resolution frequency domain experiment and a time-domain quantum beat experiment, whenever the excitation and detection steps involve electromagnetic radiation of different spectral, spatial, or temporal characteristics, the intrinsic information content of time and frequency domain experiments needs not be identical. The format in which the information is presented may be more transparently interpretable in either the time or frequency domain. 

In order to clarify the possibilities for creation of hyperthermai zones, the nonresonance (thermal) influence of electromagnetic radiation (A = 3 cm) was investigated on the model animal muscular tissues in vitro injected by nanodisperse magnetite (Figure 10.5). The mass of the tissue samples was 5 g. Samples 2 and 3 differed by the content of a small quantity of grease layer. The area of radiation was 2 cm. ... 

A review of the physical prindples of the fluorescence phenomenon permits one to understand the origins of the information content that fluorescence measurements can provide. A molecule absorbs electromagnetic radiation through a quantum mechanical process where the molecule is transformed from a ground state to an exdted state. The energy of the absorbed photon of... 

IR and microwave radiation. The one-dimensional physical model describing heat and mass transfer allows access to the temperature, moisture content and pressure fields, while energy inputs induced by electromagnetic radiation were determined by the Lambert-Beer law. A comparison of experimental and simulated results on cellular concrete demonstrated the relevance of this model to studies on combined drying.
