A wave propagating in disordered medium undergoes multiple scattering from inhomogeneities (the wave can be acoustic, electromagnetic, or it can represent an electron wave function). The scattered waves interfere with each other and, as a result, a certain intensity pattern (a speckle pattern) is ...
The wave analysis indicates that, to the three compressional waves discovered in the unsaturated porous medium, there also correspond three Rayleigh wave modes (R1, R2, and R3 waves) propagating along its free surface. The numerical results demonstrate a significant dependence of wave velocities and...
Research on SAR imaging mechanism for ocean wave propagating in azimuth direction by using numerical simulation 来自 Semantic Scholar 喜欢 0 阅读量: 54 作者:T Yoshida,CK Rheem 摘要: The SAR image simulation has been developed in the time domain to investigate a SAR imaging mechanism for moving ...
The Wave Equation If you choose a point in a medium through which a wave is propagating, the period of the wave is the time it takes that point to oscillate back to its original position. Dividing this number into 1 yields the number of times the point oscillates each second, which is ...
Detonation waves in PBX 9501 For a planar detonation wave propagating in the plastic-bonded explosive PBX 9501, measurements of the reaction zone display a classical ZND profile. Moreo... Menikoff,R. - 《Combustion Theory & Modelling》 被引量: 37发表: 2006年 ...
According to Huygens principle10, each point on a wavefront of a propagating wave is itself the source of spherical wavelets in a homogeneous medium. The wavefront in the next instant conforms to the envelope of these secondary wavelets. As depicted in Fig.2a, the aberration-free focusing re...
The fast development of mid-wave infrared photonics has increased the demand for high-performance photodetectors that operate in this spectral range. However, the signal-to-noise ratio, regarded as a primary figure of merit for mid-wave infrared detection, is strongly limited by the high dark cur...
An analytical solution is developed to the two-dimensional scattering problem of a plane-wave propagating in air, impinging on the interface with a dissipative soil, and interacting with a finite set of subsurface metallic targets. The Cylindrical Wave Approach is applied, the electromagnetic field ...
2a. For a normally incident electromagnetic wave propagating along the z-axis, strongly concentrated electromagnetic fields were generated in both the xoz- and yoz-planes with identical focal lengths of 13 mm at 38 GHz, with a full-width half-maximum focal spot size of 3.56 mm in the focal...
