Additive manufacturing of electromagnetic band gap elements
The patent application (Publication Number: US20230397340A1) describes a computerized method for fabricating an electromagnetic band gap (EBG) element using an ink jet printing system. The method involves generating a file library with 2D layer representations of the EBG element, dispensing dielectric and conductive ink compositions, forming patterns with print heads, and curing/sintering the layers to create the EBG element. The final EBG element consists of an electrically conducting ground plane, a dielectric medium, polygonal conducting elements, and gapping polygonal structures. The method also includes specific parameters for facet wall depth, distance between elements, and gap sizes to block specific frequency limits. Additionally, the patent application includes claims related to the structure of the EBG element, such as facet wall configurations and overlapping slabs, as well as an article of manufacture for fabricating the EBG element.
