The band structures of symmetrical Fibonacci sequences (SFS) composed of positive and negative refractive index materials are studied with a transfer matrix method. A new type of omnidirectional zero-<InlineEquation ID="Equ2"> <EquationSource Format="TEX">$\bar{n}$</EquationSource> </InlineEquation> gaps is found in the SFS. In contrast to the Bragg gaps, such an omnidirectional...</equationsource></inlineequation>
