Abstract

A comprehensive study on 3D printed macrostructural electromagnetic wave (EMW) absorbing structures is developed for understanding the mechanism of EMW absorption. A new composite incorporating copper solids is manufactured with printable-optimized characteristics. Two enhancing methods are developed to improve mechanical properties of 3D printed elements.
A double-layer element containing a graded nano-sized absorbent is investigated using extruded and sprayed printing. Lastly, a printed wave-shaped macrostructure is generated to fulfill the electromagnetic grading potential. The finite element analysis explore the space impedance characteristics including synthetic vector electromagnetic field and surface current distribution.
