    摘要: A system for inductively heating a workpiece may include an induction coil, at least one susceptor face sheet, and a current controller coupled. The induction coil may be configured to conduct an alternating current and generate a magnetic field in response to the alternating current. The susceptor face sheet may be configured to have a workpiece positioned therewith. The susceptor face sheet may be formed of a ferromagnetic alloy having a Curie temperature and being inductively heatable to an equilibrium temperature approaching the Curie temperature in response to the magnetic field. The current controller may be coupled to the induction coil and may be configured to adjust the alternating current in a manner causing a change in at least one heating parameter of the susceptor face sheet.

    摘要: Systems and methods to determine electromagnetic properties are provided. A particular method includes directing electromagnetic energy toward an article under test. The method also includes taking measurements of electromagnetic energy scattered by the article under test. The method further includes determining expected baseline values of at least one electromagnetic property of the article under test. The expected baseline values are based on electromagnetic energy scattered by a control article. The method also includes determining output data based on a difference between the expected baseline values and characteristic values of the article under test determined based on the measurements of electromagnetic energy scattered by the article under test. The output data includes values indicative of inhomogeneous distribution of an electromagnetic property of the article under test.

    摘要: A temperature sensor is described that includes a base, a first set of posts attached to the base having a first coefficient of thermal expansion, a second set of posts attached to the base and having a second coefficient of thermal expansion, and two substantially parallel conductive plates forming a capacitor. The first of the conductive plates is fixed to the first set of posts and the second of the conductive plates is fixed to the second set of posts. Temperature changes cause the first set of posts and the second set of posts to elongate at different rates, thereby changing a distance between the conductive plates and therefore the resulting capacitance. A system and method are also described for determining resonant frequency associated with the sensor which correlates to the temperature at the sensor when multiple sensors are networked across a system.
