A Cantor multilayer is an electromagnetic band-gap structure consisting of a stack of alternating high-/low-permittivity dielectric layers whose optical lengths follow the fractal Cantor construction. The deepest stop band is bounded by two narrow transmission peaks centered at frequencies where a strong field localization occurs inside the structure. This phenomenon also occurs if a lossy dielectric slab is inserted at the midpoint of the multilayer as a defect layer and can be conveniently used to make the field intensity inside the slab significantly stronger than the intensity of the field incident on the Cantor structure.

Abstract

A Cantor multilayer is an electromagnetic band-gap structure consisting of a stack of alternating high-/low-permittivity dielectric layers whose optical lengths follow the fractal Cantor construction. The deepest stop band is bounded by two narrow transmission peaks centered at frequencies where a strong field localization occurs inside the structure. This phenomenon also occurs if a lossy dielectric slab is inserted at the midpoint of the multilayer as a defect layer and can be conveniently used to make the field intensity inside the slab significantly stronger than the intensity of the field incident on the Cantor structure.
