This work is supported by CICYT under Project No. MAT95-0325.In this work we extend the algebraic approach introduced in the context of general Fibonacci systems [E. Maciá and F. Domínguez-Adame, Phys. Rev. Lett. 76, 2957 (1996)] to analytically study the transmission coefficient of a subset of states in the fractal Koch lattice. We report on the existence of extended states whose transmission coefficients periodically oscillate as the Koch curve approaches its fractal limit.engjournal articlehttp://dx.doi.org/10.1103/PhysRevB.57.7661https://journals.aps.org/open access538.9Spectral propertiesStatesModelsFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
