    "abstract": "The standard Kronig-Penney model with periodic $\\delta$ potentials is\nextended to the cases with generalized contact interactions. The eigen equation\nwhich determines the dispersion relation for one-dimensional periodic array of\nthe generalized contact interactions is deduced with the transfer matrix\nformalism. Numerical results are presented which reveal unexpected band spectra\nwith broader band gap in higher energy region for generic model with\ngeneralized contact interaction.",
