Cloaking strategy for Love waves

Love waves are antiplane elastic which propagate along the surface of a heterogeneous medium. Under time-harmonic regime, they governed by scalar equation Helmholtz type. We exploit invariance this governing under an in-plane arbitrary coordinate transformation to design broadband cloaks for defects. In particular, we apply elastodynamics determine anisotropic, position dependent, mechanical properties ideal able hide triangular and parabolic-shaped Dispersion analysis numerical simulations employed validate proposed strategy. Next, utilize layered monoclinic materials, with homogenized matching those cloaks, feasible triangular-shaped cloaks. The performance is validated via parametric dispersion curves, converge cloak when unit cell-wavelength ratio vanishes. Finally, confirm significant reduction defect-generated scattered fields
