The present invention relates to an electromagnetic millimetre wave absorber material, preferably having a volume resistivity of more than 1 Ωcm, containing solid particles having an aspect ratio (length:diameter) of at least 5 of a first electrically conductive material, particles having an aspect ratio (length:diameter) of less than 5 of a second electrically conductive material and an electrically non-conductive polymer, wherein the absorber material is preferably capable of absorbing electromagnetic waves in a frequency region of 60 GHz to 200 GHz and wherein the electromagnetic millimetre wave absorber material comprises based on the total amount of the absorber material from 30 wt.-% to 93 wt.-% of the electrically non-conductive polymer, from 6.5 wt.-% to 10 wt.-% of the first electrically conductive material, from 0.5 wt.-% to 0.9 wt.-% of the second electrically conductive material, and from 0 wt.-% to 59.1 wt.-% of one or more additives. The invention also relates to its use and method for absorbing as well as a sensor apparatus comprising said absorber material.
