Short summary
Large-amplitude radio waves lead to the structuring of the ionospheric plasma into groups magnetic field-aligned density cavities, or striations. A large part of the electromagnetic wave with ordinary mode polarization is then mode converted into upper hybrid waves trapped in the striations, further enforcing the striations. This simulation study investigates numerically this mode conversion and leakage of the the upper hybrid waves to back to electromagnetic waves in the Z-mode branch.
