The extinction efficiency of transparent spheres with a radial gradient of refractive index irradiated by electromagnetic plane waves was obtained by using the finely stratified sphere model [ L. Kai, P. Massoli , Appl. Opt. 33 (1994) 501–511]. The extinction efficiency of gradient‐index microspheres and location changes of morphology‐dependent resonances on the Mie extinction efficiency curves are discussed.
