A method and a device for controlling ectoparasites on animals are disclosed. Via through-holes are formed in a polyimide film between interconnects and the metal films, and the interconnects are electrically connected to the metal films. Alternatively, test lines in the deposit metal layer can be formed by laser ablation or by ultrasound erosion. Samples of interference patterns are IF-filtered to produce high spatial resolution holographic data. The superconducting filter device includes a first dielectric substrate, and a bulk superconducting resonator that is embedded in the first dielectric substrate and is formed from a bulk superconducting material. A respective pair of levers is hinged to each right-angle plate by pins; and each pair of levers is associated with a respective lock member operated from above by an operator using an actuating mechanism.
