Paper Abstract

By means of introducing defect layers into multilayer structures composed by epsilon-negative material and mu-negative material, the free modulation of single and double localized modes in zero-φeff gap is realized respectively through adjusting the thickness of different kinds of defect layers in two designed structures. In addition, the defect modes in the zero-φeff gap, being distinct from those in the Bragg gap, have the property of insensitivity to incident angle and polarization in some degree, which would be applied widely in tunable omnidirectional filters.
