.~.~ Including discontinuities within propagation means
DEFINITION
Classification: 333/153
Including discontinuities within propagation means:
(under subclass 150) Subject matter wherein abrupt modifications are included in the elastic surface wave path so as to alter the delay or transmission characteristics of the path.
(1) Note. Such discontinuities may serve as reflectors, deflectors, diffractors, phase modifiers, or mode converters.
(2) Note. Transducers distributed along the wave
transmission path to provide signal tapping functions (rather than wave perturbation) are not included here.
