 "Gaussian beams are widely used to model acoustic and optical wavefields converging to or diverging from focal regions. According to the source power and propagation distance of the Gaussian beam, particles can be trapped by the beam acoustical wave in the focal region (Wu and Du 1990; Prange and Shenoy 1996; Ding et al. 2003; Declercq et al. 2004). Most of the theoretical investigations of the Gaussian beam involve the interaction of waves with spherical particles (Wu 1991). "

ABSTRACT: Based on the finite series method, the Gaussian beam is expanded as spherical functions and the beam coefficient of a Gaussian beam is obtained. A new expression for the acoustic radiation force function, which is the radiation force per unit energy density and unit crosssectional surface area for a sphere in a Gaussian beam, is presented in this paper. Numerical results for the radiation force function of a Gaussian beam incident upon the spherical particles are presented for rigid spheres, liquid spheres and elastic spheres immersed in water to illustrate the theory. The radiation force function vs. ka curve, ka being the radius times the wavenumber in the surrounding medium, is discussed for different beam widths. The acoustic radiation force function is determined by the parameters of the particles, with liquid spheres having smaller values than those for rigid and elastic spheres. The beam width also affects the acoustic radiation force function. When the radius of the sphere is larger than the beam width, the beam width has greater effects on the radiation force. This analysis helps analyzing and understanding the effects of the acoustic Gaussian beams on spherical objects.Ultrasound in medicine & biology 09/2012; 38(11):200717.

ABSTRACT: The Rayleigh wave velocity for a coated substrate must have a value in between the ones for the substrate material and the coating material. Nevertheless, Adler and McCathern [J. Appl. Phys. 49, 2576 (1978)] have performed measurements, based on the Schoch effect, on a stainless steel substrate covered with an aluminum oxide coating that contradict this phenomenon. The current letter describes the frequency band gap effect for Rayleigh waves on coated substrates and explains how this phenomenon is related to the cited measurements. The existence of such a gap can be very important for the development of frequency filters.Applied Physics Letters 07/2004; 85(1):148150.

ABSTRACT: If a bounded beam is described using a superposition of infinite inhomogeneous waves, the values of the coefficients attributed to each inhomogeneous wave are found using a classical optimization procedure, whence it is impossible to describe the obtained values analytically. In this paper, we develop a new and easy to apply straightforward analytical method to find the appropriate values of the sought coefficients. Supplementary to its analytical and straightforward nature, the method proves to reduce the inherent instabilities found in the inhomogeneous wave decomposition.Ultrasonics 03/2005; 43(4):27982.
