Abstract
A method for the manufacture of a DRA, or an array of the DRA's, each DRA including: a substrate; and, a plurality of volumes of dielectric materials disposed on the substrate comprising N volumes, N being an integer equal to or greater than 3, disposed to form successive and sequential layered volumes V(i), i being an integer from 1 to N, wherein volume V(1) forms an innermost volume, wherein a successive volume V(i+1) forms a layered volume disposed over and at least partially embedding volume V(i), wherein volume V(N) at least partially embeds all volumes V(1) to V(N−1), the method including: forming on the substrate a first volume of the plurality of volumes of dielectric materials from a first dielectric material having a first dielectric constant; and, forming over the first volume a second volume of the plurality of volumes of dielectric materials with a second dielectric material having a second dielectric constant.
