Transmission properties of fractal Cantor distribution with left-handed materials
【摘要】 Transmission properties of fractal Cantor distribution with left-handed materials (LHM) are investigated. The transmittance and reffectance spectra can be calculated by using the optical transmission matrix method. Comparing with the conventional Cantor multilayers, these structures with LHM have double functions of stopbands and defects. Through adjusting the thickness of dielectric layers, the properties of stopbands and defects can be obtained, respectively. For stopbands, a broad stopband filter is studied. For defect modes, multi-frequencies narrow passband filters are proposed.
