Two parameter texture of nearly bimaximal neutrino mixing

We propose a texture of a three generation Majorana-type neutrino mass matrix in terms of only two parameters which gives rise to nearly bimaximal mixing angles. We also demonstrate an explicit realization of such a type of neutrino mass-matrix in the context of an ${\mathrm{SU}\left(2\right)\mathrm{}}_L\times {\mathrm{U}\left(1\right)\mathrm{}}_Y$ model due to higher-dimensional mass terms through the inclusion of discrete $Z_3\times Z_4$ symmetry and two extra singlet Higgs fields.
