چکیده
Abstract Temporal discontinuity in a medium’s dielectric properties (temporal boundary) is useful model for considering electromagnetic phenomena dynamic materials and metamaterials. Here counterpart of the Ewald–Oseen extinction theorem classical optics derived light scattering at temporal boundary. In particular, it shown that initial wave its replacement by frequency shifted waves gas-plasma boundary can be understood as result superposition elementary scattered suddenly appeared individual free electrons. contrast to theorem, closely related causality transient effects; field any observation point formed arriving from sphere expanding with speed light.

Boundary-Aware Extinction Mapping
We introduce Boundary-Aware Extinction Maps for interactive rendering of massive heterogeneous volumetric datasets. Our approach is based on the projection of the extinction along light rays into a boundary-aware function space, focusing on the most relevant sections of the light paths. This technique also provides an alternative representation of the set of participating media, allowing scatte...
متن کاملExtinction theorem for object scattering in a stratified medium
A simple relation for the rate at which energy is extinguished from the incident wave of a far field point source by an obstacle of arbitrary size and shape in a stratified medium is derived from wave theory. This relation generalizes the classical extinction theorem, or optical theorem, that was originally derived for plane wave scattering in free space and greatly facilitates extinction calcu...
متن کاملA uniqueness theorem for a boundary inverse problem
Let DcR' be a bounded domain with a smooth boundary r, A u + q ( x ) u = O in D u = f , u N = h on Iand ~ ( x ) E L ~ ( D ) . From knowledge of the set {f, h} where f runs through C'(r) the coefficient 9(x) is uniquely recovered. Analytical formulae for y(x) are given. Applications are considered. Let D c R3 be a bounded domain with a smooth boundary r, q(x) E L"(D) , A u + q ( x ) u = O in D U...
متن کاملBlaschke's Rolling Theorem for Manifolds with Boundary
For a complete Riemannian manifold M with compact boundary ∂M denote by C∂M the cut locus of ∂M in M . The rolling radius of M is Roll(M) := dist(∂M, C∂M ). Let Focal(∂M) be the focal distance of ∂M in M . Then conditions are given that imply the equality Roll(M) = Focal(∂M). This generalizes Blaschke’s rolling theorem from bounded convex domains in Euclidean space to more general Euclidean dom...
متن کاملTemporal dynamics of recovery from extinction shortly after extinction acquisition.
Evidence suggests that extinction is new learning. Memory acquisition involves both short-term memory (STM) and long-term memory (LTM) components; however, few studies have examined early phases of extinction retention. Retention of auditory fear extinction was examined at various time points. Shortly (1-4 h) after extinction acquisition spontaneous recovery was high compared to that after long...
