简介
The feasibility of tailoring the lattice constant to manipulate the scattering behavior of periodic dielectric particles is examined at the microwave band. In the proposed structure, alumina spheres with square lattices are embedded into cardboards. Multipole modes of spherical particles are excited by incident plane waves. Lattice-tailored interactions can enhance or eliminate forward or backward scatterings of particle arrays to realize transparency or opacity properties. Non-resonant and resonant interactions are investigated in detail, and results indicate a large group delay can be obtained by resonant Kerker transparency. The proposed methodology shows robustness and application potentials from the microwave to optical band.
