Theoretical Study of Negative Material Bias Index Symptoms

Abstract

Theoretical research on the phenomenon of negative refractive index material
was cunducted. The material is a known metamaterial that can manipulate electromagnetic
waves through it. By changing the permeability and permittivity of a medium that is worth
imaginary, then the value is included in the equation will produce a refractive index that is
negative. This value can be achieved through material forms are designed so that the
magnetic field and electric field manipulation. The equation used on electromagnetic waves
that Maxwell's equations, is revealed to be some similarities propagation magnetic field and
electric field. The Methods Finite Difference Time Domain (FDT D) as a modifier equation
was then equations analysis, simulated using MatlabR2014 program. Based on simulation
results, visible when the electromagnetic waves through a material metamaterial, the waves
are deflected, do not pass part of the material covered.
