Abstract: A stereolithography method of manufacture of a polymer structure having a spatially gradient dielectric constant, including: providing a volume of a liquid, radiation-curable composition; irradiating a portion of the liquid, radiation-curable composition with activating radiation in a pattern to form a layer of the polymer structure; contacting the layer with the liquid, radiation-curable composition; irradiating the liquid, radiation-curable composition with activating radiation in a pattern to form a second layer on the first layer; and repeating the contacting and irradiating to form the polymer structure, wherein the polymer structure comprises a plurality of unit cells wherein each unit cell is integrally connected with an adjacent unit cell, each unit cell is defined by a plurality of trusses formed by the irradiation, wherein the trusses are integrally connected with each other at their respective ends, and the trusses of each unit cell are dimensioned to provide the spatially gradient dielectric constant.

Abstract: An electromagnetic, EM, device, includes: a three-dimensional, 3D, body having a dielectric material, the 3D body having a first dielectric portion, 1DP, and a second dielectric portion, 2DP, wherein the 1DP is at least partially but not completely embedded within the 2DP; wherein the 1DP and the 2DP each have a dielectric material other than air; wherein the 1DP and the 2DP each have a planar cross-section profile perpendicular to a particular linear axis of the 3D body that is constant along the particular linear axis; wherein at least a portion of the 3D body is a dielectric resonator, DR.
