Reviewer 2 Report

The authors studied the dynamical Casimir effect with anisotropic scatterers. The new approach—Hamiltonian approach—is exploited to calculate the DCE by a moving anisotropic scatterer within the dipolar approximation. This approach has no need to assume the infinite metallic surface, which is necessary condition for the traditional ap- proach to learn the DCE. This extension could give a more realistic results compared with the traditional one. As pointed out by the authors, the infinite plate calculation over- estimates the photon production rate by many orders. Therefore, this approach is very important for learning the DCE. The authors considered two examples as an application of their formalism: a finite-size mirror oscillating at a typical mechanical frequency; the dynamical Casimir photons produced by a metallic oscillating rod. Interesting results has been shown. The whole manuscript is well-written, and all the expressions are clear. Therefore, I recommend this manuscript for publication in Entropy journal. There is a comment:

1) it is more interesting to discuss the case where the disk oscillates along the direction neither perpendicular nor parallel to its surface, while with a fixed angle?
