quarterwave造句

• This is because the quarterwave transforms the infinite impedance into a zero impedance.
• The quarterwave length of wire can be regarded as an artificial earth for RF purposes.
• In 1938, George Brown et al . patented a loop antenna with rhombic shape and quarterwave sides.
• Such a polarization controller can for example be obtained by placing on the optical path three rotatable waveplates in cascade : a first quarterwave plate, which is oriented to transform the incident elliptical polarization into linear polarization, a halfwave plate, which transforms this linear polarization into another linear polarization, and a second quarterwave plate, which transforms the other linear polarization into the desired elliptical output polarization.
