Published 7 April 2003. Physics. Optics express. The mathematical solution for Cerenkov radiation in a novel medium, left-handed medium (LH medium), which has both negative permittivity and permeability, is introduced in this paper. It is shown that the particle motion in the LH medium generates power that propagates backward. WebMay 9, 2024 · Miniaturization of the unit cell was achieved by increasing the capacitance and inductance. The electric and magnetic response can also be tuned by varying the length of the CLS. The structure has simultaneous negative permittivity and permeability, which produce a wide double negative band to any polarized incident wave. kibys colombia
