In this work, we consider potential energy of recently conceptualized optimal (balanced) bianisotropic particles in electromagnetic fields. The case of non-resonant lossless particles is studied. Knowing the potential energy of optimal bianisotropic particles in the fields of the respective excitations, we find the acting force on the particle in inhomogeneous external fields. It is found that for optimal particles with the balanced values of the polarizabilities the potential energy and acting force are time independent.
Key words: Bianisotropic particle / Electromagnetic wave / Potential energy
