MAGNETOSTATIC WAVE FILTER DEVICE

摘要

The invention relates to devices utilizing magnetostatic waves. The invention has as its object a filter microtape which is able to pick up and selectively dissipate magnetostatic waves as a function of their wavelength. The filter microtape is permeable to waves of which the wavelength is a submultiple of its width. The invention is applicable in particular to tunable magnetostatic wave devices such as delay lines, resonators and oscillators.
