Quasi-BICs due to symmetry mismatch in architected elastic plates
Adib Rahman, Sean Perkins, Raj Kumar Pal
We report the existence of quasi-bound modes in the continuum (quasi-BICs) in architected elastic plates based on a square lattice. The structure consists of topologically trivial…

Observation of elastic bound modes in the continuum in architected beams
Adib Rahman, Raj Kumar Pal
We report the experimental observation of an elastic bound mode in the continuum (BIC) in a compact region of an architected beam. We consider a long slender beam with rigid masses…
