Note on I-brane near horizon PP-wave background

We find out a PP-wave spacetime with constant Neveu-Schwarz (NS) three form flux by taking a Penrose limit on the (1+1)-dimensional intersection of two orthogonal stacks of fivebranes in type IIB string theory. We further find out an intersecting (D1-D5)-brane solution in this background and analyze its supersymmetry properties by solving the dilatino and gravitino variations explicitly.
