Electromagnet

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

See YIG sphere and Electromagnet

A ferrimagnetic material is a material that has populations of atoms with opposing magnetic moments, as in antiferromagnetism, but these moments are unequal in magnitude, so a spontaneous magnetization remains.

See YIG sphere and Ferrimagnetism

Jewellery

Jewellery (or jewelry in American English) consists of decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants, bracelets, and cufflinks.

See YIG sphere and Jewellery

Loop antenna

A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor, that for transmitting is usually fed by a balanced power source or for receiving feeds a balanced load. YIG sphere and loop antenna are Wireless tuning and filtering.

See YIG sphere and Loop antenna

Magnetic field

A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

See YIG sphere and Magnetic field

Microwave

Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves (as originally discovered) but longer than infrared waves. YIG sphere and Microwave are Microwave technology.

See YIG sphere and Microwave

Preselector

A preselector is a name for an electronic device that connects between a radio antenna and a radio receiver. YIG sphere and preselector are Wireless tuning and filtering.

See YIG sphere and Preselector

Q factor

In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is.

See YIG sphere and Q factor

Resonator

A resonator is a device or system that exhibits resonance or resonant behavior.

See YIG sphere and Resonator

Signal processing

Signal processing is an electrical engineering subfield that focuses on analyzing, modifying and synthesizing signals, such as sound, images, potential fields, seismic signals, altimetry processing, and scientific measurements.

See YIG sphere and Signal processing

Single crystal

In materials science, a single crystal (or single-crystal solid or monocrystalline solid) is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries.

See YIG sphere and Single crystal

Spectrum analyzer

A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument.

See YIG sphere and Spectrum analyzer

Tumble finishing

Tumble finishing, also known as tumbling or rumbling, is a technique for smoothing and polishing a rough surface on relatively small parts.

See YIG sphere and Tumble finishing

Yttrium iron garnet

Yttrium iron garnet (YIG) is a kind of synthetic garnet, with chemical composition, or Y3Fe5O12. YIG sphere and Yttrium iron garnet are Iron(III) compounds.
