2. RF probe - Wikipedia

   en.wikipedia.org/wiki/RF_probe

   An RF probe is a device which allows electronic test equipment to measure ... In 1980 Reed Gleason and Eric Strid invented the first high frequency wafer probe while ...

3. Cascade Microtech - Wikipedia

   en.wikipedia.org/wiki/Cascade_Microtech

   In the early 1980s, Eric W. Strid and K. Reed Gleason, employees at Tektronix (Tek), attempted to get their bosses to make a microwave wafer probe for testing microchips. [3] Management declined, but did license the technology to the two, leading to the formation of Cascade Microtech in 1982 on a part-time basis.

4. Non-contact wafer testing - Wikipedia

   en.wikipedia.org/wiki/Non-contact_wafer_testing

   These methods use tiny RF antennae (similar to RFID tags, but on a much smaller scale) to replace both the mechanical probes and the metal probe pads. If the antennae on the probe card and IC are properly aligned, then a transmitter on the probe card can send data wirelessly to the receiver on the IC via RF communication.

5. EMF measurement - Wikipedia

   en.wikipedia.org/wiki/EMF_measurement

   A mono-axial, omnidirectional probe is a device which senses the Electric (short dipole) or Magnetic field linearly polarized in a given direction. Using a mono-axial probe implies the need for three measurements taken with the sensor axis set up along three mutually orthogonal directions, in a X, Y, Z configuration. As an example, it can be ...

6. Microwave cavity - Wikipedia

   en.wikipedia.org/wiki/Microwave_cavity

   A microwave cavity or radio frequency cavity (RF cavity) is a special type of resonator, consisting of a closed (or largely closed) metal structure that confines electromagnetic fields in the microwave or RF region of the spectrum. The structure is either hollow or filled with dielectric material. The microwaves bounce back and forth between ...

7. Radio-frequency engineering - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_engineering

   Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.

   On May 12, 2023, Extreme Meteorologist Reed Timmer and his team accomplished an exceptionally difficult task -- intercepting a tornado in an armored vehicle. The terrifying and groundbreaking ...

9. Time-domain reflectometer - Wikipedia

   en.wikipedia.org/wiki/Time-domain_reflectometer

   The TDR method is a transmission line technique, and determines apparent permittivity (Ka) from the travel time of an electromagnetic wave that propagates along a transmission line, usually two or more parallel metal rods embedded in soil or sediment. The probes are typically between 10 and 30 cm long and connected to the TDR via coaxial cable.
