    • In a surface wave isolator consisting of two gyromagnetic slabs a conductive strip between said slabs, means to establish a magnetizing field within said slabs, a two part load is associated side by side with said slabs and the strip extends also between the two parts of the load. A first part of the load is a continuous load parallel to the strip, a second part of the load is a plurality of localized absorbing means placed along the propagation axis and parallel to said strip. The impedance of the localized absorbing means is matched to the impedance of an unwanted parasitic propagation mode at the corresponding place.
    • 在由两个回旋钢板组成的表面波隔离器中,在所述板之间的导电带,在所述板之间建立磁化场的装置,两部分负载与所述板并排连接,并且所述带还延伸在所述板的两个部分之间 加载。 负载的第一部分是平行于带的连续载荷,负载的第二部分是沿着传播轴线平行放置的多个局部吸收装置。 局部吸收装置的阻抗与相应位置的不需要的寄生传播模式的阻抗相匹配。

    • A tunable microwave bandstop filter device comprises a main microwave transmission line (1), at least one filter cell comprising a coupled line segment (4) coupled to the main transmission line (1) and arranged parallel to and remotely from the latter, and also a tunable LC resonant circuit (5, 6). According to the invention, the tunable LC resonant circuit (5, 6) is placed between one of the ends of the line segment (4) and the main microwave transmission line (1).
