  1. 1. Optical metasurfaces for momentum exchange between light and matter

    Författare :Mohammad Mahdi Shanei; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical forces and torques; phase-gradient metasurface; particle transport; optical momentum exchange; Flat optics; rotary meta-motor; meta-particle;

    Sammanfattning : Light carries energy and momentum that can be transferred to matter. Because of the conservation of total momentum, a change in light momentum due to interaction with an object must be compensated by an equal but opposite change in the momentum of that object. LÄS MER

  3. 2. Momentum exchange between light and nanostructured matter

    Författare :Daniel Andrén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-gradient metasurface; optical force and torque; metavehicle; momentum exchange.; nano-optics; rotary nanomotor; optical tweezers;

    Sammanfattning : An object's translational and rotational motion is associated with linear and angular momenta. When multiple objects interact the exchange of momentum dictates the new system's motion. LÄS MER
