Tóm tắt

Mie resonances in dielectric particles play a crucial role in light-matter interaction, characterized by strong multipolar optical responses and low dissipative losses. This study presents an innovative methodology for precise discrimination of the size and quantity of deep-subwavelength microspheres by leveraging Fano resonances in coupled magnetic-dipole (MD) modes of a CaTiO
