Wideband Dispersive Surface Wave Filters.
Abstract
The results of this program clearly demonstrate that broadband, large dispersion reflective array filters can be readily implemented, noniteratively, based on a simple design model. With careful control on filter fabrication and measurement, corrections in the phase response can be introduced to achieve a high sidelobe suppression capability. To the small extent that 'ideal' performance was not achieved in the present device, the inadequacies proved to be associated with the transducer rather than reflective grating limitations. From the excellent agreement between theory and measurement, it is safe to conclude that it is quite feasible to achieve required transducer equalization through non-iterative compensations in the reflective grating design.
