Abstract

We study the tunneling problem from general Smith-Volterra-Cantor (SVC) potential of finite length LL characterized by the scaling parameter ρ\rho and stage GG. We show that the SVC(ρ\rho) potential of stage GG is the special case of super periodic potential (SPP) of order GG. By using SPP formalism developed by us earlier, we provide the close form expression of tunneling probability TG(k)T_{G}(k) with the help of qq-Pochhammer symbol. The profile of TG(k)T_{G}(k) with wave vector kk is found to saturate with increasing stage GG. Very sharp transmission resonances are found to occur from this system which may find applications in the design of sharp transmission filters.
