Valerij, Доктор технічних наук Registration Date 21-01-2004 Organization Research Institute of Applied Electronics of Natoinal Technical University of Ukraine "KPI" popup.description2 Work is devoted to making of a mathematical sample piece of shear modes in a monolithic piezoelectric ceramic core. On his base, the deflectors with high frequency of cavity oscillations for scanning a laser beam in technological systems (systems of thermal action on substances is offered a converting element due to a surfacing a laser radiation, systems of medical application, others) and at gauging physical properties with the help of a light beam (system of noncontact gauging of linear dimensions, system of ecological monitoring, others). Such base scientific and applied results are in-process received: -The mathematical sample piece of drive of shear modes in a piezoelectric ceramic monolithic core designed due to making system of mutual electric field on its sides; -Methods of the assaying of resonant properties of the composite combined designs on a base of piezoelectric ceramic are offered; -Principles of making of an electromechanical element of the transformer in an optical deflector of a high-frequency band on a base of a piezoelectric effect in a solid body designed; -Topological plans of electrodes for effective drive of shear modes in a monolithic core are fulfilled; -The technology of drawing of exciting electrodes on monolithic piezoelectric a ceramic core designed and tested on the experimental sample piece; -Circuitries of drive of shakings with parts of neutralization designed. The scientific report on work contains: -Mathematical sample piece of drive of shear modes in a monolithic piezoelectric ceramic core; -Alternatives of designs of topological plans of electrodes for effective drive of shear modes in a monolithic core; -The description of a master schedule of manufacture of a piezoelectric ceramic monolithic core and drawing of exciting electrodes on his side. The received results enable to create a new class monolithic a deflectors on a base of volumetric electromechanical oscillations with basic new characteristics and technological approaches. Waste at performance of the design expedients of drive of shear modes with the help of a special pattern of an electric field can be effectively used for making new devices, transformers and sensor controls on a base of the functional substances in electronic systems and devices. The mathematical sample pieces received in-process, technological expedients and constructive solutions will be useful to making functional devices of microelectromechanical systems (МEMS) at the operations of the electronic and defensive industry.
