New sensors of magnetic induction in near field, dedicated to studies of electromagnetic compatibility, are proposed according to the principle of the Standard CISPR16-1 coils. The new coil shape allows the sensors to be sensitive to only some specific components of the multipolar expansion, which is similar to a spatial filtering. Our proposition follows previous works. By means of rotations of the spherical harmonics functions, our aim is to simplify the geometry of the sensor coils introduced before. After a description of the tools required, the design method is described. Comparative robustness studies end the article.
