The principle uses the natural height, length and breadth of natural or forced air convection cooling fms used in the cooling of electronic assemblies to form a matrix of waveguides operating beyond their cut off frequency. This may then be used to provide attenuation to tf. fields when the heatsink assembly forms a vent in an electrically screened enclosure. Figure 1 illustrates a typical example of an enclo- sure utilizing such a device.
