surface acoustic wave coupling coefficient
- surface acoustic wave coupling coefficient
- коэффициент связи пьезоэлектрического фильтра на поверхностных акустических волнах
коэффициент связи пьезоэлектрического фильтра на поверхностных акустических волнах (Kc2, Ks2)
Величина, являющаяся мерой взаимного преобразования электрической энергии в механическую и, наоборот, приблизительно равная удвоенному значению относительной разности фазовых скоростей поверхностных акустических волн на свободной и металлизированной поверхности пьезоэлектрика.
Примечание
Значение коэффициента связи определяют по формуле
,
где 
- относительное изменение скорости, вызванное закорачиванием поверхности электрода.
