A wave‐based hybrid ray‐mode algorithm has recently been developed to parametrize mid‐ and high‐frequency sound scattering from submerged empty and simply loaded cylindrical shells [Felsen et al., J. Acoust. Soc. Am. 87, 554–569 (1990)]. Th

Fully three‐dimensional Green’s functions are important for synthesizing the acoustic scattering response from submerged spherical shells due to excitation not only by actual radiating sources without special symmetries but also by induced source

Radiation and diffraction problems in open regions (with infinite cross section) are usually solved in terms of integral representations for the fields which cannot be evaluated in closed form. In many applications, however, the integrands contain a

In a companion paper [L. B. Felsen and Y. P. Guo, J. Acoust. Soc. Am. 94, ⧠⧠ (1993)], two‐dimensional acoustic wave scattering from a thin elastic cylindrical shell with internal loading has been expressed in terms of a hybrid ray‐mode algori

A phenomenologically based hybrid ray‐mode synthesis strategy is applied here to reconstruct the backscattered field from a submerged thin cylindrical elastic shell with internal structural loadings, which is insonified by a normally incident time

A recently formulated geometrical theory of diffraction for coherence functions of high-frequency fields propagating in a random medium is applied here to the canonical problem of line-source field diffraction by a perfectly reflecting wedge. The sol

Curved dielectric layers, either by themselves or as claddings on perfectly conducting substrates, are useful elements for guiding and confining electromagnetic energy. The prototype configuration, explored here, has circular cylindrical symmetry. Th

The earth's environment contains propagation channels wherein waves can be guided because of the presence of transverse boundaries or transverse refractive index gradients. By a new approach, high-frequency guiding by a single concave surface or by t

Ray acoustic and adiabatic mode representations provide effective means for charting sound transmission in relatively complicated propagation and diffraction environments, under operating conditions that validate the use of such approximate waveforms
