Abstract: A method for forming three-dimensional periodic lattice structures through the use of additive manufacturing to achieve engineered, application specific, effective material properties that differ from that of the bulk host 3d-printable material for radio frequency (RF) applications including radomes and antenna apertures. Such structures remain mechanically robust while offering access to a range of material properties not available otherwise through the engineering of detailed wave-propagation characteristics through such lattice structures.
