Abstract: To study radio wave propagation in tunnels, we present a vectorial parabolic equation (PE) taking into account the cross-section shape, wall impedances, slowly varying curvature, and torsion ...

Abstract: Using two-dimensional numerical simulations, interaction of a counter-propagating probe laser pulse with a relativistic electron mirror formed with an accelerating laser from a plasma layer ...

Nonetheless, concerns persist regarding their environmental impact and the risk of propagating low-quality information, especially with large language models (LLMs). Join us for the launch of the ...
