They run at a resonance frequency of f0=1.3GHz and are operated in the standing-wave π-mode, where the direction of the accelerating electric field alternates from cell to cell when observed at a certain moment, as illustrated in the top sketch. The cell length lc=c∕(2f0) is chosen...
Magneto-elasto-electric (ME) coupling heterostructures, consisting of piezoelectric layers bonded to magnetostrictive ones, provide for a new class of electromagnetic emitter materials on which a portable (area ~ 16 cm2) very low frequency (VLF) transmitter technology could be developed. The proposed...
A) Find the frequency at which a 250 mH inductor has a reactance of 400 ohms. B) At what frequency would a .40 mu F capacitor have at the same reactance? What inductor in series with a 140-ohm resistor and a 2.3-microfarad capacitor will...
At what frequency does the inductive reactance of a 57.0 μH inductor equal the capacitive reactance of a 57.0 μF capacitor? Resonant frequency: It is the frequency where the capacitive reactance of a capacitor and the inductive reactance ...
