20100214176 | RADIATION ATTENUATION - A device for attenuating electromagnetic radiation in a desired transmission frequency band. The device includes a generally planar substrate, and a resistive pattern arranged on the substrate adapted to reflect a proportion of incident radiation in the transmission band. The resistive pattern may be screen printed using carbon based ink. This provides a simple, cheap and easy to fabricate device which can quickly and easily be affixed to the exterior of an antenna or antenna housing to attenuate the power of radiation in the transmission band, resulting in reduced range or sensitivity. | 08-26-2010 |
20120207612 | WIND TURBINE BLADES - A wind turbine blade includes a multilayer composite structure including a first reflective layer, and a second layer including a plurality of resistive circuit analogue (CA) elements. The CA elements are tuned so as to interact with said first layer to provide absorption of electromagnetic (EM) energy over a desired frequency range. The parameters of the CA elements can be varied to provide for frequency tuning and to maintain absorption at a specific frequency range despite varying layer separation, while at the same time ensuring that the mechanical properties of the CA layer are compatible with integration into the turbine blade. | 08-16-2012 |

20120025111 | ELECTROMAGNETIC FIELD ABSORBING COMPOSITION - This invention relates to the field of an electromagnetic (EM) field absorbing composition, in particular, those capable of providing absorbance in the frequency of commercial radar. The composition finds particular use as a radar absorbing coating for wind turbines, in particular for use in onshore and offshore environments. There are further provided coated surfaces comprising the composition, methods of absorbing EM radiation, and methods of use of such a composition, such that a surface coated in the composition is capable of absorbing EM radiation. There is provided an electromagnetic radiation absorbing composition comprising elongate carbon elements with an average longest dimension in the range of 50 to 1 000 microns, with a thickness in the range of 1 to 15 microns and present in the range of from 0.5 to 20 volume % dried, in a non conductive binder. | 02-02-2012 |
