摘要： A method includes depositing a first metal layer on a semiconductor substrate; etching the first metal layer to form a first electrode having a first lead; depositing a piezoelectric layer on the semiconductor substrate and first electrode; etching the piezoelectric layer to a shape of the gyrator to be formed within the circulator; depositing a second metal layer on the piezoelectric layer; etching the second metal layer to form a second electrode having a second lead, the second electrode being positioned opposite the first electrode, wherein the first lead and the second lead form an electrical port; depositing a magnetostrictive layer on the second electrode; etching the magnetostrictive layer to approximately the shape of the piezoelectric layer; depositing a third metal layer on the magnetostrictive layer; and etching the third metal layer to form a metal coil that has a gap on one side to define a magnetic port.

摘要： An impedance matching device comprising a variable reactor having a main winding and control winding, wherein a generated magnet field in the core is an AC magnetic field with a magnitude exceeding a value to settle a deviation between a control target value for impedance matching and a feedback value, by changing the magnitude of the generated magnetic field by changing a control current passing through the control winding, thereby controlling inductance of the variable rector to be a predetermined value to perform impedance matching, the response delay in the impedance matching is reduced by reducing a response delay in the inductance variation of the variable reactor.

摘要： An electrostatically tunable magnetoelectric inductor including: a substrate; a piezoelectric layer; and a magnetoelectric structure comprising a first electrically conductive layer, a magnetic film layer, a second electrically conductive layer, and recesses formed so as to create at least one electrically conductive coil around the magnetic film layer; with a portion of the substrate removed so as to enhance deformation of the piezoelectric layer. Also disclosed is a method of making the same. This inductor displays a tunable inductance range of >5:1 while consuming less than 0.5 mJ of power in the process of tuning, does not require continual current to maintain tuning, and does not require complex mechanical components such as actuators or switches.
