摘要： PURPOSE: To make a device simple and small in size, to shorten the measuring time, and to improve the measuring accuracy by projecting the lower part of an electric wave shielding plate to a sample placing surface side from a surface for linking each horn surface of transmission and reception, and shielding a direct wave from a transmitting horn.
CONSTITUTION: A transmitting horn 20 is placed in the upper part of a base K so that an electric wave transmitted from its horn part 20a becomes a necessary incident angle θ
1 against an axis Ka of a sample base K, and also a receiving horn 30 is positioned at the upper part than the horn 20 and placed, on a line having an angle of reflection equal to the angle θ
1 against the axis Ka. Also, on the axis Ka being a middle part of the horn 20 and 30, an electric wave shielding plate 40 is placed in a state that its lower part 40u is projected to a sample placing surface (a) side from a surface for linking each horn surface of the horn 20 and 30. Accordingly, a direct wave from the horn 20 is cut off by the plate 40.

摘要翻译：目的：为了使装置尺寸简单，尺寸小，缩短了测量时间，并通过将电波屏蔽板的下部投影到样品放置表面侧，从而将每个喇叭表面连接起来，从而提高测量精度发射和接收，并屏蔽来自发射喇叭的直接波。构成：将发射喇叭20放置在基座K的上部，使得从其喇叭部20a传递的电波相对于试样基体K的轴线Ka成为必要的入射角θ1，接收喇叭30为位于比喇叭20的上部，并且放置在具有相对于轴线Ka的角度θ1的反射角的线上。此外，在作为喇叭20,30的中间部的轴Ka上，电波屏蔽板40被放置在其下部40u从用于连接各个部件的表面投影到样品放置面（a）侧的状态喇叭20和30的喇叭表面。因此，来自喇叭20的直接波被板40切断。

摘要： PURPOSE:To sharpen more a received picture pattern and to prevent surely generation of ghost or the like by fitting a radio wave shield in parallel with irradiated direction of a radio wave to the peripheral of a parabolic antenna main body. CONSTITUTION:The radio wave shield body 20 consists of a cylindrical main body 21 made of an FRP, a radio wave absorbing layer 22 provided to cover the inner circumference of the main body 21 and a radio wave shield layer 23 provided to cover the peripheral face of the main body 21. The inner diameter of the main body 21 is made nearly coincident with the inner diameter of a peripheral part 10a of the parabolic antenna main body 10 and the thickness is a thickness offering the required strength to the said radio wave shield 20. Thus, the electromagnetic wave from a communication satellite is reflected in the surrounding buildings or the like and a reflected wave R1 is about to invade into the parabolic antenna main body 10, but it is reflected or grounded by the radio wave shield body 20 or absorbed and attenuated and the invasion into the parabolic antenna main body 10 is shut off.
摘要翻译：目的：通过将无线电波屏蔽与无线电波的辐射方向并联安装到抛物面天线主体的周边，来增加更多的接收到的图像图案并防止确实产生重影等。构成：无线电波屏蔽体20由FRP制成的筒状主体21，覆盖主体21的内周的无线电波吸收层22和覆盖主体21的周面的电波屏蔽层23构成主体21的内径与抛物面天线主体10的周边部10a的内径大致一致，厚度为向所述无线电波屏蔽提供所需强度的厚度因此，来自通信卫星的电磁波被反射在周围的建筑物等中，并且反射波R1即将侵入到抛物面天线主体10中，但是它被无线电波屏蔽体20反射或接地或被吸收和衰减，并且入侵到抛物面天线主体10中被切断。
