摘要: [1] We demonstrate here, for the first time, that scattering of a shear Alfven wave (SAW) having long perpendicular wavelength (λ⊥), with localized density cavity, generates perturbations in field structures like expected from radiation pattern an resonance cone (AWRC) emitted sources. Such SAW-cavity interaction provides novel mechanism generating narrow inertial waves those observed satellites and variously called solitary, kinetic dispersive waves.
