Abstract :
A practical set of engineering design equations are derived for predicting stopband performance of electromagnetic-bandgap (EBG) structures within parallel power planes. The EBG circuits suppress the TEM-mode noise within parallel plates used within digital power distribution networks. Stopbands are realized over designed frequency bands of interest in the microwave spectrum. The mathematical relationships between the physical hardware and the electrical models are clearly stated. Several examples are given and proof-of-concept experiments are described and compared to the predicted results with good agreement.
