PML reflect surface wave on metal/air interface

I am simulation a single electric dipole radiation on a single air/metal interface. the domain is surrounded by PML layer,layer thickness equals to 1 wavelength and the material property of PML layer is the same with adjacent material (so PML being air in the upper part and being metal in the lower part).
However, I found reflection from PML layer. The reflection can be clearly seen if I plotted Poynting Vector 2D surface. the direction of array is pointing towards the center in metal surface.
Another evidence is that electric field is not zero at the position of dipole normal to the interface(dipole direction is y aixs), and interference pattern can be seen in the air domain.
Could anyone please tell if what to do and how to solve this problem.
Best regards,
