Patent attributes
Electromagnetic attenuation of an object is accomplished by attaching a boot to a surface of an operational part of the object. The boot includes a thermoplastic material, such as in a thermoplastic layer, and an electromagnetic attenuation material, such as in an electromagnetic attenuation layer that overlies at least part of the thermoplastic layer. The attaching is accomplished by placing the boot onto the operational part, and then heat shrinking the boot to attach the boot to the operational part. The electromagnetic attenuation layer may have gaps in it prior to the heat shrinking, gaps that are closed during the heat shrinking, to the greater contraction of the thermoplastic layer. The boot and method may be used to advantageously provide electromagnetic attenuation without a need for spraying processes. The method may be used to retrofit and/or repair an object, without needed to remove it from the field.
