Webthrough-Wall (LSW) experimental setups consisted of two radio-frequency cavities. We compare the e ciencies of three setups which involve the cavity pump modes and external magnetic elds. Additionally, we discuss the sensitivity dependence both on the relative position of two cylindrical cavities and on their radius-to-length ratio. 1 Introduction WebThe resonance of cavity mainly concentrates on the long cylindrical part of the funnel-shaped cavity. Thus the diameter of the long cylindrical part of the funnel-shaped cavity is respectively chosen as 2 mm, 3 mm and 4 mm. The corresponding sound absorption curves are given in Fig. 20 (b). It is seen that the diameter of the long cylindrical ...
