Nonstationary random acoustic and electromagnetic fields as wave diffusion processes*
We investigate the effects of relatively rapid variations of the boundaries of an overmoded cavity on the stochastic properties of its interior acoustic or electromagnetic field. For quasi-static variations, this field can be represented as an ideal incoherent and statistically homogeneous isotropic random scalar or vector field, respectively. A physical model is constructed showing that the fi...
متن کاملCorrespondence Principle in a PP-wave Background
We discuss the correspondence point between a string state and a black hole, in a pp-wave background, and find that the answer is considerably different from that in a flat spacetime background.
متن کاملLocal spectral time-domain method for electromagnetic wave propagation.
We explore the feasibility of using a local spectral time-domain (LSTD) method to solve Maxwell's equations that arise in optical and electromagnetic applications. The discrete singular convolution (DSC) algorithm is implemented in the LSTD method for spatial derivatives. Fourier analysis of the dispersive error of the DSC algorithm indicates that its grid density requirement for accurate simul...
متن کاملElectromagnetic Fields and the Precautionary Principle
While for substances that may be detrimental to health if incorporated through the skin, or by inhalation or ingestion precautionary procedures have been developed in the past decades that are applied in a transparent and standardised way by health authorities, public health agencies and international organisations in order to protect the public from a potential health hazard, no such procedure...
متن کاملStructure from Motion Without Correspondence: General Principle
A general principle is given for detection of the 3D structure and motion from an image sequence without using point-to-point correspondence. The procedure consists of two stages: ( i ) determination of the "flow parameters" from "features" without using correspondence and ( i i ) computation of the 3D structure and motion from these flow parameters. The f i r s t stage is done by solving equat...
