A multi-physics null medium that performs as a perfect endoscope for both electromagnetic and acoustic waves is designed by transformation optics, which opens new way to control simultaneously. Surface multi-physics, novel graphical method design devices, proposed based on the directional projecting feature of medium. Many including beam shifters, scattering reduction, imaging devices steering can be simply in surface-corresponding manner. All surface only need one homogeneous anisotropic (null medium) realize, approximately implemented brass plate array without any artificial sub-wavelength structures. Numerical simulations are given verify performances made array.
