Electromagnetic forces in the time domain
Optics Express, 2022 We look beyond the standard time-average approach and investigate optical forces in the time domain. The formalism is developed for both the Abraham and Minkowski momenta, which appear to converge in the time domain. We unveil an extremely rich – and by far unexplored – physics associated with the dynamics of the optical forces, which can even attain ...

Electromagnetic Force on a Magnetic Monopole [PDF]
Progress of Theoretical Physics, 1984 The electromagnetic force on a magnetic monopole in matter is shown to be F=g(H-v\ifmmode\times\else\texttimes\fi{}E/c) when there is only one magnetic monopole in matter. The relation between this force and the conservation law of momentum is discussed. The case in which a macroscopic number of magnetic monopoles exist in matter is also discussed.

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Improved strategies of the Equality Set Projection (ESP) algorithm for computing polytope projection [PDF]
Mechanical SciencesThis paper proposes an optimization method for the Equality Set Projection algorithm to compute the orthogonal projection of polytopes. However, its computational burden significantly increases for the case of dual degeneracy, which limits the ...
