FIG. 6B depicts the example attenuation interface 610 with an outer perimeter 612 surrounding an inner perimeter 614 that is at least partially composed of an EMI absorber. In this example, the inner perimeter 614 extends past an inner surface 616 of a side wall 618. In some examples, an inner flange 619 is implemented to align, retain and/or position the inner perimeter 614.

FIG. 6C depicts the example attenuation interface 620 that is similar to the example shown in FIG. 6B, but with an inner perimeter 622 partially extending past an inner surface 624 of a side wall 626, but also extending to an inner depth of the side wall 626.

FIG. 6D depicts the example attenuation interface 630. In the illustrated example, an EMI absorber 632 is surrounded by walls 634, which are at least partially composed of metal. In some such examples, the EMI absorber 632 fits into (e.g., is placed into) a recess (e.g., a complementary shaped recess) 636 of a shield and/or housing.

Turning to FIG. 6E, the example attenuation interface 640 is shown. In this example, an outer perimeter 642 surrounds an inner perimeter 644 having an EMI absorber. The example inner perimeter 644 exhibits a generally dovetail-shaped and/or irregular cross-sectional profile 646 to be received by a complementarily shaped recess 647 of the outer perimeter 642. In the illustrated example, the dovetail-shaped cross-sectional profile 646 includes a first portion 648 that is smaller than a second portion 649.
