Abstract

Janus particles are microscopic objects characterized by one feature with dual properties. Typical examples are metal-coated Janus particles, widely used in soft and active matter applications because of their versatility and their fabrication simplicity. Janus particles are often utilized in the presence of optical potentials. Here, we provide an implementation for calculating forces and torques on partially coated Janus particles of spherical and ellipsoidal shape in the geometrical optics approximation. We first validate our model against the known experimental results and show that interesting effects arise in the presence of travelling-wave optical potential.
