Optical tweezers (OTs) can transfer light momentum to particles, achieving the precise
manipulation of particles through optical forces. Due to the properties of non-contact and …

Optical tweezers (OTs), which generate a variety of fascinating beam patterns, allow
biologists to uncover the natural secrets of human life at single-cell level. Due to its gentle …

It is well established that the interaction of light with matter generally imparts mechanical
forces and associated torques. Where laser light is involved, such effects can be deployed …

We employ neural networks to improve and speed up optical force calculations for dielectric
particles. The network is first trained on a limited set of data obtained through accurate light …

The forces acting on an isotropic microsphere in optical tweezers are effectively
conservative. However, reductions in the symmetry of the particle or trapping field can break …

The highly focused laser beam is capable of confining micro-sized particle in its focus. This
is widely known as optical trapping. The Janus particle is composed of two hemispheres …

Measurement of trapping force with Shack Hartmann sensor, which is done in this paper,
offers many advantages. It opens a way for phase and force measurement at the same time …

Light pressure was first recognized by Kepler [1] in its explanation of comets tail. Its
understanding lies within the theory of electromagnetism by Maxwell [2] and the …

The aim of this thesis is to discuss theoretical approaches and numerical results suitable for
describing some phenomena that characterize the interaction between electromagnetic …
