Electromagnetic bandgap (EBG)

Electromagnetic Bandgap (EBG) refers to a design feature in materials or surfaces that block or significantly reduce electromagnetic waves—like radio frequencies—within specific frequency ranges. Think of it as a specialized “filter” embedded in surfaces or circuits that prevents certain signals from passing through or propagating. This helps improve device performance by reducing interference, managing electromagnetic energy, and controlling signal propagation. EBG structures are used in antennas, circuits, and shielding applications to optimize their function and ensure signals behave predictably without unwanted noise or interference.
