Abstract
An apparatus includes an object and one or more sensors located adjacent to or in the object. The object is formed of a material whose dielectric constant or magnetic permeability has a negative real part at microwave-frequencies. The one or more sensors are located adjacent to or in the object and measure an intensity of an electric or a magnetic field therein.
Claims15
An apparatus, comprising:
- an object formed of a material in which one of the dielectric constant and the magnetic permeability has a value with a negative real part at microwave frequencies;
- and
- one or more sensors located adjacent to or in the object and configured to measure an intensity of an electric or magnetic field therein;
- and
- wherein the value of the real part causes the object to respond resonantly to external electric or magnetic fields.
2 more elements
A method, comprising:
- exciting an object by receiving microwave radiation therein, the object being formed of a material in which one of a dielectric constant and a magnetic permeability has a value with a negative real part at microwave frequencies;
- and
- detecting a field intensity internal or adjacent to the object in response to the object being excited by the microwave radiation;
- and
- wherein the receiving produces a resonant response in one of a magnetic field intensity in the object and an electric field intensity in the object.
