• Network Analyzer System
• Free space measurements (NRL Arch) ( 2 GHz to 18 GHz)
• Coaxial line/Waveguide Characterization (complex mu and epsilon ) ( 100 MHz to 12GHz)
• Vibrating Magnetometer System
• Large Magnet System: > 15000 Oe
• Oven for measurements: up 700 Degrees Centigrade
• Magnetic measurements of hysteresis, anisotropy, moment, coercivity, remanence…
• RF Spectrum Analyzer system:
• Frequency range 110MHz to 18 GHz
• Antenna probes for magnetic RF fields

The Vibrating Sample Magnetometer is of the Foner design with GPIB interface and LabVIEW computer control system.

• The system has a basic sensitivity of 10^-3 emu, & with special techniques, <10^-5 emu.
• The system includes an oven for measurements up to 700 degrees Kelvin.
• Interfaces to LABView allow complex data analysis of unprocessed data.

Polar Materials has a Heavy Magnet facility that can provide very uniform magnetic fields.

• Measurement volume is a cylindrical space of 6" in diameter by 2" in width for homogeneous fields..
• Fields of over 15,000 Gauss can be obtained in this volume. This magnet weighs almost 4,000 pounds!

The Three Phase Power supply is capable of supplying 75 amps at 150 volts DC to the water cooled magnet.

For material characterization an NRL Arch/DosTek "T" system is available that measures

the reflection from the surface of flat samples.

• 8 to 12 GHz frequency range. This is a specular measurement and can be made at various angles of incidence and separation ( Transmission horn to sample).
• System noise floor of about -50 dB compared to a metal plate reflection and > 40 dB of dynamic range for characterization.
• Standard horns are used for the measurements as well as wide band absorber to lower the noise floor.
