Scattering of electromagnetic radiation by a multilayered sphere

Answer»

puter implementation of the algorithm for the calculation of electromagnetic radiation scattering by a multilayered sphere developed by Yang, is presented. It has been shown that the program is effective, resulting in very accurate values of scattering efficiencies for a wide range of size parameters, which is a considerable improvement over previous implementations of similar algorithms. The program, named scattnlay, would be the first of its kind to be publicly available.Program summaryProgram title: scattnlayCatalogue identifier: AEEY_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AEEY_1_0.htmlProgram obtainable from: CPC Program LIBRARY, Queen's University, Belfast, N. IrelandLicensing provisions: Gnu General Public License (GPL)No. of lines in DISTRIBUTED program, including test data, etc.: 8932No. of bytes in distributed program, including test data, etc.: 175 276Distribution format: tar.gzProgramming language: ANSI CComputer: Any with a C compilerOperating system: Linux (any), Windows, SolarisRAM: ∼1–100 MBClassification: 1.3Nature of problem: The scattering of electromagnetic (EM) radiation by a multilayered sphere is an interesting phenomenon to study for the application of such materials in several fields. Just to mention two examples, metal nanoshells (a dielectric core surrounded by a metallic SHELL) are a class of nanoparticles with tunable optical resonances that can be used, among others, in medicine for optical imaging and photothermal cancer therapy; while in the field of atmospheric sciences, light absorption by aerosols has a heating effect in the atmosphere that is of great interest to study several climatic effects. Although at first glance the expressions of the scattering coefficients seem simple and straightforward to implement, they involve several numerical difficulties which make most of the existent algorithms inapplicable to several extreme cases. More recently, Yang [1] has developed an improved recursive algorithm that circumvents most of the numerical problems present in previous algorithms, which is implemented in the current program.Solution method: Calculations of Mie scattering coefficients and efficiency factors for a multilayered sphere as described by Yang [1], combined with standard solutions of the scattering amplitude functions.Restrictions: Single scattering, permeability of the layers is always unity.

How we know inverse square law is given by coulombforce?

Answer»

. Coulomb's law states that: The magnitude of the electrostatic force of attraction or repulsion between TWO point charges is directly proportional to the product of the magnitudes of charges and inverselyproportional to the square of the distance between them. The inverse-square law, in physics, is any physical law stating that a specified physical quantity or INTENSITY is inversely proportionalto the square of the distance from the source of that physical quantity. The fundamental cause for this can be understood as geometric dilution corresponding to point-source radiation into three-dimensional space (see diagram).Radar energy expands during both the signal transmission and also on the reflected return, so the inverse square for both paths means that the radar will RECEIVE energy according to the inverse fourth power of the range.In order to prevent dilution of energy while propagating a signal, certain methods can be used such as a waveguide, which acts like a canal does for water, or how a gun barrel restricts hot gas EXPANSION to one dimensionin order to prevent loss of energy transfer to a BULLET.

Find the relation between current density and electric field

Answer»

c fields CAUSE charges to move. It stands to reason that an electric field applied to some material will cause currents to flow in that material. For an AMAZINGLY wide range of materials, an EMPIRICAL rule called Ohm's law gives the FOLLOWING relation between current DENSITY and applied electric field: J = σ E .

Why is it considered important to obtain the balance point near the midpoint of the wire

Answer»

y, balance point of wire is the point where torque must be zero. according to rotational dynamics , we know torque acts along centre of mass of the system equals zero. e.g., centre of mass is located midpoint of wire. as you can calculate by using basic concepts of centre of mass. (0,0)A----------------------------B(L,0)let AB is wire of LENGTH L and mass m.cut an element of mass DMSO, dm = m/L DX now, centre of mass, x = = = hence, centre of mass of wire is located at midpoint of the wire. so, torque along midpoint of the wire equals zero. that's why, it is considered that balance point near the midpoint of the wire.
