This utility model discloses a vibration damping device, wall panel, and mechanical equipment based on a Mikaelian lens. The vibration damping device based on a Mikaelian lens includes: a conformal self-focusing lens; a vibration damping element disposed on a portion of the conformal self-focusing lens corresponding to at least one wave focus; and / or an energy harvesting element disposed on a portion of the conformal self-focusing lens corresponding to at least one wave focus. Thus, by disposing of the vibration damping element and / or the energy harvesting element on the portion of the conformal self-focusing lens corresponding to at least one wave focus, or on a portion of the conformal self-focusing lens adjacent to at least one wave focus, the vibration damping element can suppress vibrations transmitted to the conformal self-focusing lens, and the energy harvesting element can collect and utilize the vibrational energy transmitted to the conformal self-focusing lens.
