Light Scattering and Absorption by Particles: The Q-Space Approach - (Sorensen Christopher M.)(Pevná vazba) - diskuze

How electromagnetic radiation such as light is scattered or absorbed by media is used in many fields as it can provide information on the size, shape, number, and dynamics of particles or objects. It is key to fields as diverse as physical chemistry, materials science, nanotechnology, microbiology, astronomy, atmospheric sciences and radar. This is not purely an academic concern, most aerosol mass in the atmosphere, including entrained mineral dust, volcanic ash, and soot consists of particles with irregular shapes and the way they scatter and absorb light has implications for many climate models. One new approach considers the scattering in reciprocal or Q-space. Q-space analysis has been used extensively in the fields of small angle x-ray and neutron scattering but developments in scattering, in general, and light scattering in particular, are relatively recent. This book provides a thorough overview of how particles of any size or shape scatter and absorb light. Its conceptual basis is unique and founded on the fact that light is first and foremost a wave and then also an electromagnetic wave. Thus the wave phenomenon of diffraction underlies all scattering, and the electromagnetic character of light causes the scattering to evolve away, in a systematic manner, from the diffraction limit. The mathematics of diffraction is the Fourier transform which links real space to reciprocal space, which we call Q-space. The Fourier variable q is related to the scattering angle in ex
