The advanced microwave sounding unit ( AMSU) is a multi-channel microwave radiometer installed on meteorological satellites. The instrument examines several bands of microwave radiation from the atmosphere to perform atmospheric sounding of temperature and moisture levels. Flooding from Hurricane Isidore shown by AMSU channel 2.
Waveguide post filter: a band-pass filter consisting of a length of WG15 (a standard waveguide size for X band use) divided into a row of five coupled resonant cavities by fences of three posts each. The ends of the posts can be seen protruding through the wall of the guide. A waveguide filter is an electronic filter constructed with waveguide ...
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 ...

The first modern horn antenna in 1938 with inventor Wilmer L. Barrow. A horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horns are widely used as antennas at UHF and microwave frequencies, above 300 MHz. [ 1]
The patient should remain in the ice bath until their body temperature falls to 102.2 degrees. Then, they can be transported to the hospital. Preparing for heat illness in a warming world
Atmospheric temperature trends from 1979–2011 based on satellite measurements. Microwave Sounding Unit temperature measurements refers to temperature measurement using the Microwave Sounding Unit instrument and is one of several methods of measuring Earth atmospheric temperature from satellites. Microwave measurements have been obtained from ...
Escherichia virus T4 is a species of bacteriophages that infect Escherichia coli bacteria. It is a double-stranded DNA virus in the subfamily Tevenvirinae of the family Straboviridae . T4 is capable of undergoing only a lytic life cycle and not the lysogenic life cycle .
