Abstract |
Consider a magnetized ferrite-wire waveguide structure situated between two half free spaces. Ferrites
to provide negative permeability and wire array to provide negative permittivity. The structure form left -
handed material (LHM) with negative refractive index. The transmission of electromagnetic waves
through the structure is investigated theoretically. Maxwell's equations are used to determine the electric
and magnetic fields of the incident waves at each layer. Snell's law is applied and the boundary conditions
are imposed at each layer interface to calculate the reflected and transmitted powers of the structure. Numerical
results are illustrated to show the effect of frequency, applied magnetic fields, angle of incidence
and LHM thickness on the mentioned powers. The analyzed results show that the transmission is very
good when the permeability and permittivity of the structure are both simultaneously negative. The frequency
band corresponding to this transmission can be tuned by changing the applied magnetic fields. The
obtained results are in agreement with the law of conservation of energy.
