електромагнітне розсіяння

Моделювання середовища із заданою магнітною проникністю на основі асимптотичного розв'язку задачі електромагнітного розсіяння

The problem of scattering of electromagnetic (EM) waves by many small impedance particles (bodies), embedded in a homogeneous medium is studied in order to create medium with desired permeability. Physical properties of the particles are described by their boundary impedance. The limiting integral equation is obtained for the effective EM field in the limiting medium, at a → 0 , where a is the characteristic size of a particle and M ( ) a is the number of particles. The proposed approach allows one to create a medium with a desirable spatially inhomogeneous permeability.
