Two parallel Dipole Antenna separated by lambeda/2

Find the currents 𝐼1 and 𝐼2 on two parallel scattering dipoles having a length of half a wavelength 𝜆/2 , as a function of the distance 𝑑 between them, for a given incident plane wave with angle of incidence 𝜃𝑖𝑛 and a given polarization (see figure below). To make things easier, as a starting point: If (𝑍𝐿 = 0) on the dipoles and solve also if angle incidence and solve the problem 𝜃𝑖𝑛 = 0 and phi/4 consider two case and show plotting diagram ?
