Abstract
A method and an apparatus for filtering radio-frequency electromagnetic beams, in particular x-rays, include a fluid container containing a ferrofluid which at least partially absorbs the electromagnetic beams. A distribution of the ferrofluid within the fluid container can be varied by using an applied magnetic gradient field. An irradiation apparatus and a device for irradiating an object are also provided.
