"This research presents an application of the resistive frequency selective surface (FSS) fabricated with a 3D printed conductive material as an electromagnetic absorber for the EMI-reducing door. This solution allows to reduce radiated emissions of a router system. The resistive frequency selective surface has a three-layer structure. The top layer is a 3D printed FSS pattern, the middle layer is an air gap, and the bottom layer is a metal plane.

The first paper presents the methodology for manufacturing a frequency selective surface using the 3D printing technology, including the material characterization, design, fabrication, and evaluation.

The unpublished content presents the results of applying the 3D printed resistive frequency surface to a mock up of a router system. The prototype is evaluated in terms of the reflection coefficient and total radiated power measurements. After that it is attached to the EMI-reducing door and tested on the router system mock up"--Abstract, page iv.
