Abstract:
The scattering waves by two elastic spheres in solid are studied. The incident wave, the scattering waves in the host and the transmitted waves in the elastic spheres are all expanded in the series form of spherical wave functions. The total waves are obtained by addition of all scattered waves from individual elastic sphere. The addition theorem of spherical wave function is used to perform the coordinates transform for the scattering waves from different spheres. The expansion coefficients of scattering waves are determined by the interface condition between the elastic spheres and the solid

Abstract:
We experimentally examine a laser-induced underwater shock wave paying special attention to the pressure impulse, the time integral of the pressure evolution. Plasma formation, shock-wave expansion and the pressure in water are observed simultaneously using a combined measurement system that obtains high-resolution nanosecond-order image sequences. These detailed measurements reveal a distribution of the pressure peak which is not spherically symmetric. In contrast, remarkably, the pressure impulse is found to be symmetrically distributed for a wide range of experimental parameters, even when

Abstract:
The formulation of generalize electromagnetic scattering is given. Previously derived multipole expansions using the language of scattering are presented and applied to resonant and plasmon resonances. Formal scattering theory is introduced, and the integral scattering equation is derived and used to find the Born expansion and to prove the optical theorem. Partial wave analysis for the scaler scattering problem is discussed with connections between quantum (wave theory) and classical views. Vector spherical harmonics and the extension of partial wave analysis to the scattering of vector fields of electromagnetic waves are presented. Finally, Mie scattering is considered in detail with applications including glory scattering and whisper gallery mode resonances.

Abstract:
The spectroscopy of diatomic molecules (Herzberg, 1950) serves as a paradigm for the study of larger molecules. In our presentation of the algebraic approach we shall follow a similar route. An important aspect of that presentation is the discussion of the connection to the more familiar geometrical approach. In this chapter we survey those elements of quantum mechanics that will be essential in making the connection. At the same time we also discuss a number of central results from the spectroscopy of diatomic molecules. Topics that receive particular attention include angular momentum operators (with a discussion of spherical tensors and the first appearance of the Wigner-Eckart theorem which is discussed in Appendix B), transition intensities for rovibrational and Raman spectroscopies, the Dunham expansion for energy levels, and the Herman- Wallis expansion for intensities. Two-body quantum mechanical systems are conveniently discussed by transforming to the center-of-mass system. The momentum (differential) operator for the relative motion is . . .p = − iħ∇ . . . . . .(1.1). . . where ∇ is the gradient operator whose square ∇ • ∇ is the Laplacian and, as usual, i2 = − 1 and ħ is Planck’s constant/2π.

Abstract:
This chapter examines how boundary and geometry affect convection. It begins with a discussion of how one can implement “absorbing” top and bottom boundaries, which reduce the large-amplitude convectively driven flows within shallow boundary layers or the reflection of internal gravity waves off these boundaries in a stable stratification. It then considers how to replace the impermeable side boundary conditions with permeable periodic side boundary conditions to allow fluid flow through these boundaries and nonzero mean flow. It also introduces “two and a half dimensional” geometry within a cartesian box geometry and describes how a fully 3D cartesian box model could be constructed. Finally, it presents a model of convection in a fully 3D spherical-shell and shows how it can be easily reduced to a 2.5D spherical-shell model. The horizontal structures are represented in terms of spherical harmonic expansions.
