Summary:
In this paper, a multilayered cylinder filled with metamaterials is studied. General formulas of electromagnetic fields in each region are derived using the eigenfunction expansion method. For an infinite line source, the image property is observed when the radius of this cylinder is much larger than the wavelength. The distributions of electromagnetic fields are presented when a line source is placed near a two-layered cylinder alternately filled with double negative (DNG) and double positive (DPS) material. The electric field and energy in the presence of a cylinder with very small radius have been investigated.
