Phononic crystals are structures with discontinuous dispersion relations, such as crystals made of atoms. A. Bergamini and co‐workers show on page 1343 that in adaptively augmented phononic crystals, existing bandgaps can be canceled at specific frequencies by modifying the mechanical connectivity of the unit cell.
