Method for creating and tuning electromagnetic bandgap structure and device

摘要

Tuned Electromagnetic Bandgap (EBG)devices (10, 30), and a method for making and tuning tuned EBG devices (10, 30) are provided. The method includes the steps of providing first and second overlapping substrates (32, 32a), placing magnetically alignable conductive material (36) between the substrates (32, 32a), and applying a magnetic field (44, 45) in the vicinity of the magnetically alignable conductive material (36) to align at least some of the material into conductive vias (46, 47). The method further includes the steps of physically altering via characteristics of EBG devices (10, 30) to tune the bandpass and resonant frequencies of the EBG devices (10, 30).
