Dependence of the intensity of the non-wave component of extreme UV waves on the coronal magnetic field configuration Open
Mounting evidence has shown that extreme-ultraviolet (EUV) waves consist of a fast-mode magnetohydrodynamic (MHD) wave (or shock wave) followed by a slower non-wave component, as predicted by the magnetic field line stretching model. Howev…

Fractional Fourier transform of Airyprime beams Open
Analytical expressions of the electric field, the centriod, the beam half width, and the linear momentum of the fractional Fourier transform (FrFT) of an Airyprime beam are derived, respectively. The relation between the centriods or the b…
