Protecting MRI rooms by dielectric diffraction gratings

Nowadays in order to protect against the waves available in surrounding MRI rooms we use mu-metal. We suggest to use 1D dielectric gratings to protect MRI rooms from surrounding mobile waves. Hence, we present a grating with maximum reflection by RCWA method.
