Ultrasonic guided waves in bone

The Journal of the Acoustical Society of America, 2008
Recent progress in quantitative ultrasound (QUS) has shown increasing interest towards measuring long bones by ultrasonic guided waves. This technology is widely used in the field of non-destructive testing and evaluation of different waveguide structures.

Optical Guided-Wave Devices

Science, 1986
Optical fiber is rapidly becoming the transmission medium of choice for new telecommunication systems. For a true lightwave network to evolve, however, optical control devices such as optical switches and multiplexer-demultiplexers will be essential.

An annular wave-guide rotary joint with wave-guide feed

Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1954
THERE are many engineering problems in the field of electronics which require a good method of transmitting radio frequency energy from a fixed unit to a rotating unit. For radio frequencies at which wave guides are normally employed, the rotary joint herewith described is especially suitable, particularly where there is a multiplicity of independent ...
