The types of platonic structures that have been examined include arrays of perforations, arrays of pins, arrays of point masses, as well as periodic variations in the plate material itself. Platonic crystals have been shown to exhibit a number of behaviours similar to photonic crystals, including

where wave propagation is not possible through the crystal, as well as cloaking near degenerate band surfaces. Investigations into defective platonic crystals has also revealed strong energy localization effects within the defects, with high
