Defect modes in one-dimensional magnetized plasma photonic crystals with a dielectric defect layer

By using transfer matrix method, properties of one-dimensional magnetized plasma photonic crystals with a dielectric defect layer are studied. Results show that several defect modes appear within the photonic band gaps; periodic number and collision frequency only affect transmission magnitude of the defect modes; the external magnetic field and incident angle control both the transmission magnitude and frequency of the defect modes; thickness and dielectric constant of the defect layer determine both the number and frequency of the defect modes. This phenomenon may be useful in designing of narrow band filters or multi-channel filters. (c) 2012 American Institute of Physics. [doi:10.1063/1.3677876]
