wave scattering 예문

• Danish physicist Ludvig Lorenz and others independently developed the theory of electromagnetic plane wave scattering by a dielectric sphere.
• The scattering is assumed to be " s "-wave scattering, and therefore spherically symmetric.
• This is an analogue to analytical solution for the scattering of electromagnetic radiation, or electromagnetic plane wave scattering, by spherical particles-dielectric spheres.
• Electromagnetic wave scattering was calculated and simulated for the layered ( metamaterial ) structure and the split-ring resonator anistropic metamaterial, to show the effectiveness of the layered metamaterial.
• Wave numbers and wave vectors play an essential role in optics and the physics of wave scattering, such as X-ray diffraction, neutron diffraction, and elementary particle physics.
• This has major applications in communications, radar wave scattering, etc . His methods have also been used in creating special effects for movies such as Harry Potter and The Core.
• If we consider only s-wave scattering the differential cross section does not depend on the angle \ theta, and the total scattering cross section is just \ sigma = 4 \ pi | f | ^ 2.
