Proton Acceleration with Relativistic Electromagnetic Shock

open access: yesAdvanced Science, EarlyView.
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Multi‐Mechanical Regulation of 3D Printed Triply Periodic Hyperbolic Surfaces via Fourier Synthesis‐Based Free Modeling

open access: yesAdvanced Science, EarlyView.
Arbitrary structural regulations of triple periodic hyperbolic surfaces are achieved using mathematical Fourier construction and 3D printing technology, enriching the geometric forms and achieving optimized mechanical behaviors. Abstract Triply periodic hyperbolic surfaces (TPHSs) have attracted significant attention due to their exceptional ...
