Claim 21:
22. An article of manufacture comprising a non-transitory memory storage device storing thereon a computer readable medium (CRM) for fabricating an electromagnetic band gap (EBG) element, the CRM comprising a set of executable instructions configured to, when executed by at least one processor, cause the at least one processor to perform the steps of:
a. receiving the 3D visualization file representing the EBG element;
b. generating a file library having a plurality of files, each file representing a substantially 2D layer for printing the EBG element, and a metafile representing at least the printing order of each of the substantially 2D layers for printing;
c. obtaining from the library a first file representing a first printing layer of the EBG element, the first file comprising printing instructions for a pattern representative of at least one of: the dielectric ink, and the conductive ink;
d. using a first print head, in communication with the at least one processor, operable to dispense dielectric ink, included with the article of manufacture in communication with the at least one processor, forming a pattern representative of the dielectric ink in the first printing layer of the EBG;
e. using an electromagnetic radiation source in communication with the at least one processor, curing the pattern corresponding to the dielectric ink in the first layer;
f. using a second print head operable to dispense conductive ink, in communication with the at least one processor, forming a pattern representative of the conductive ink in the first printing layer of the EBG;
g. using a focused heat source in communication with the at least one processor, sintering the pattern corresponding to the conductive ink in the first layer;
h. obtaining from the library a subsequent file representative of a subsequent layer for printing the EBG element; the subsequent file comprising printing instructions for a pattern representative of at least one of: the dielectric ink, and the conductive ink in the subsequent layer;
i. repeating the steps of: forming the pattern corresponding to the dielectric ink in the subsequent layer, to the step of sintering the pattern corresponding to the conductive ink in the subsequent layer, wherein upon curing and/or sintering a final layer, the EBG element is configured to comprise:
i. an electrically conducting ground plane having an apical surface and a basal surface
ii. a dielectric medium having a basal surface and an apical surface disposed over the electrically conducting ground plane;
iii. a plurality of polygonal conducting elements each having an apical surface and a basal surface disposed adjacently to, and distanced from each other on the apical surface of the dielectric medium, each polygonal conducting element further comprises at least two opposing facet walls extending basally, wherein each conducting element is coupled to the electrically conducting ground plane by a blind via; and
iv. a plurality of gapping polygonal structures each associated with a polygonal conducting element and having an apical surface, the gapping polygonal structure extending apically from the apical surface of the electrically conducting ground plane, wherein each gapping polygonal structures defining a concentric bore wherein the blind via is disposed coaxial with the bore.
