Active Feedback-Driven Defect-Band Steering in Phononic Crystals with Piezoelectric Defects: A Mathematical Approach
Defective phononic crystals (PnCs) have garnered significant attention for their ability to localize and amplify elastic wave energy within defect sites or to perform narrowband filtering at defect-band frequencies. The necessity for continuously tunable defect characteristics is driven by the varia...
