Abstract :
We discuss electromagnetic fields and optical forces acting on microspheres made of extremely anisotropic medium. We propose an energy-based criterion for choosing an appropriate solution of Maxwell´s equations inside the sphere when two solutions are singular at the center. We investigate the material parameters of a lossy hyperbolic-metamaterial sphere that can be pulled by a nonparaxial, gradientless Bessel beam.
