This contribution presents numerical and experimental results on a 2nd order UHF filter prototype that exploits helical resonators with modulated radius.
Resonators are the single most important ingredient in microwave and radio frequency circuits.
Previous studies have shown that there are simple relationships between the helical twist sense, spontaneous polarization direction, and orientational ordering in ferroelectric liquid crystals.
We address, using probabilistic modeling and the extreme-value-distribution technique, the helicopter undercarriage strength in a helicopter-landing-ship situation.
We have used a graphite fiber as a substrate to study the kinetics of desorption and sticking of (4)He for temperatures between 15K and 1.6K.
Helix waveguide, composed of closely wound turns of insulated copper wire covered with a lossy jacket, shows great promise for use as a communication medium.

A telephone switching system that employs electronic components and reed switches to the exclusion of electromechanical devices can be described as quasi-electronic.
Single mode fibers with hermetic carbon coatings were evaluated for their high temperature loss stability and for their performance in hydrogen atmospheres.
