This is probably where the term absorption cross section comes from. As we mentioned, it has nothing to do with the geometric cross section of the fiber. We also need to note that the absorption cross section does not mean attenuation; it indicates the efficiency of energy conversion from ...
It has been shown that the absorption in the shell can be approximated by an effective cross-section which can be expanded in a polynomial in the thickness of the shell. The effect of truncating the polynomial by another polynomial of lower order has been discussed. Formulae for the ...
RADAR CROSS SECTION (RCS) Radar cross section is the measure of a target's ability to reflect radar signals in the direction of the radar receiver, i.e. it is a measure of the ratio of backscatter power per steradian (unit solid angle) in the direction of the radar (from the target)...
As a related molecular characteristic the collision cross section (CCS) is therewith obtained, reflecting the two dimensional projection of the sphere that is formed by the randomly rotating ionized molecule in the gas phase. Mathematically this can be described by the Mason-Schamp equation21,22,...
In this lesson, you will learn how a solid with a known cross section is created. Then, you will learn how to set up the integral that helps you...
Finding the volume of the region using the slicing method and note that the basic formula fot the volume is {eq}\displaystyle V=A\times l {/eq} where {eq}A {/eq} is the area of the cross-section and {eq}l {/eq} ...
The pure cross-anisotropy is understood as a special scaling of strain (or stress). The scaled tensor is used as an argument in the elastic stiffness (or c
A 'Constant Cross Section' refers to a design feature where the cross-sectional area of an object remains the same along its entire length to ensure uniformity and consistency in its structure or composition. AI generated definition based on: Fusion Technology 1990, 1991 ...
Section snippets Formulation We consider a domain Ω in the three-dimensional Euclidean space R3 with a conical boundary C (Fig. 1). The cone is assumed to be convex which leads to some simplifications of the theory. Let the two-dimensional unit sphere S2 be the surface of the ball of ra...
