Examines transverse kink modes in 3D curved coronal loops

Eigenfrequencies deviate ∼10% from WKB theory in uniform loops

In stratified loops, horizontal modes deviate more (∼25%)

Lateral leakage is present but weaker than resonant damping

Transverse kink oscillations in curved solar loops

This paper examines transverse (horizontally & vertically polarized) kink oscillations in curved solar coronal loops embedded in a potential magnetic field. 3D MHD simulations find the eigenfrequencies deviate ∼10% from analytical WKB theory in uniform loops. In stratified loops, horizontal modes deviate further (∼25%), likely due to asymmetric density profiles. Despite some lateral leakage, resonant absorption dominates the damping in both cases.
