We demonstrate the emergence of classical features in electronic quantum transport for the scanning gate microscopy response in a cavity defined by a quantum point contact and a micron-sized circular reflector. The branches in electronic flow characteristic of a quantum point contact opening on a two-dimensional electron gas with weak disorder are folded by the reflector, yielding a complex spatial pattern. Considering the deflection of classical trajectories by the scanning gate tip allows to establish simple relationships of the scanning pattern, which are in agreement with recent experimental findings.

Author comments upon resubmission

Dear editors,
As requested, we have included in our manuscript a link to reproducibility-enabling resources. We herewith resubmit the new version for publication in SciPost.
Best regards,
Dietmar Weinmann

List of changes

A paragraph "Reproducibility-enabling resources" with a link to a folder on the cloud of our institute has been added after the Funding information and before the Appendices.
