Grazing Behavior of Scatter and Propagation Above Any Rough Surface
At grazing, propagation and scatter become inextricably connected. For sufficiently low source/observer heights, free-space inverse-distance propagation no longer applies and plane-wave descriptions of scatter give way to surface-wave modes. Concepts like surface radar cross section must be reinterpreted; lack of awareness of these facts in attempts to correlate measurements with grazing-angle ...
متن کاملOn Coherent Structures of Turbulent Open-channel Flow Above a Rough Bed
Present study examines turbulent structures of a rough bed open-channel flow in the context of deterministic approach. Instantaneous velocity field is measured in different hydraulic conditions using two dimensional Particle Image Velocimetry (PIV) in vertical plane and Stereoscopic PIV in horizontal plane. Different techniques and quantities such as swirl strength, two-point and cross-correlat...
متن کاملProbing a Random Medium with a Pulse *
This paper studies the reflection of pulses from a randomly layered half space. It characterizes the statistical properties of the reflected signals at the surface in a suitable asymptotic limit in which the pulse width is large compared to the typical size of the inhomogeneous layers but small compared to the macroscopic variations of the medium properties. It is shown how this characterizatio...
متن کاملSCATTER : A New Dimension in Side-Channel
Side-channel techniques have well progressed over the last few years, leading to the creation of a variety of statistical tools for extracting the secrets used in cryptographic algorithms. Such techniques are taking advantage of the side-channel traces collected during the executions of secret computations in the product. Noticeably, the vast majority of side-channel attacks requires the traces...
متن کاملEfficient Radio Propagation Prediction Al- Gorithm including Rough Surface Scatter- Ing with Improved Time Complexity
Precise modeling of radio propagation is necessary for experiencing the benefits of wireless technology for indoor environments. Among many modeling techniques, the ray tracing based prediction models become popular for indoor wireless radio propagation characterization. Though the ray tracing models are popular, their key deficiency is the slower performance. In this paper, an accelerated tech...
