In order to further understand the characteristics of PMN-PT piezoelectric single crystal
materials, the piezoelectric constant d 33, impedance and frequency characteristics of PMN …

The ocean is opaque to electromagnetic radiation and transparent to low frequency sound,
so acoustical methodologies are an important tool for sensing the undersea world …

Waves traveling through random media exhibit random focusing that leads to extremely high
wave intensities even in the absence of nonlinearities. Although such extreme events are …

A ray-based wave-field description is employed in the interpretation of broadband basin-
scale acoustic propagation measurements obtained during the Acoustic Thermometry of …

Several acoustic experiments show a surprising degree of stability in wave fronts
propagating over multi-megameter ranges through the ocean's sound channel despite the …

Abstract The Garrett–Munk (GM) spectrum continues to be a useful description of the
oceanic internal wave field. However, there are several inconsistencies and ambiguities that …

A series of long-range acoustic propagation experiments have been conducted in the North
Pacific Ocean during the last 15 years using various combinations of low-frequency, wide …

In underwater acoustics, the accuracy of computational field predictions is commonly limited
by uncertainty in environmental parameters. An approximate technique for determining the …

Recently, textured piezoelectric ceramics have become a hot topic in the field of
piezoelectric materials. Due to their high cost-effectiveness, textured ceramics are expected …

This document entitled “Trends in Nuclear Explosion Monitoring Research and
