Linked and knotted beams of light, conservation of helicity and the flow of null electromagnetic fields

, 2010
Maxwell's equations allow for some remarkable solutions consisting of pulsed beams of light which have linked and knotted field lines. The preservation of the topological structure of the field lines in these solutions has previously been ascribed to the

Behaviour and mechanisms of molecular vibrations induced by a pulsed voltage in a silicone elastomer used for device encapsulation

High Voltage, 2023
Silicone elastomers are widely used to encapsulate power electronic devices. However, such devices may be subjected to square‐wave pulsed voltages with a high rate of change, which can create significant challenges for encapsulation insulation.
