The Mie field calculation of a coated sphere has significance in photonic and biomedical applications, but roundoff errors are often critical. Such pitfalls can be circumvented by arbitrary precision scheme. The extended Mie theory shows spherically symmetric optical heating in laser–liposome interactions. It also predicts a penetrating standing wave in a silver-coated silica microsphere in water...
Nanoshells are useful in near-infrared (NIR) applications because of the red shift of the Mie resonance into NIR. Silica/gold/silver nanoshells were prepared via gold anchoring and characterized by Mie-theoretical calculations and transmission electron microscopy, which indicated a broad and enhanced NIR absorption and a partially coated, mottled Ag/Au structure on the silica core. The mottled nanoshells...
