摘要： PROBLEM TO BE SOLVED: To provide a composition for a radio wave absorbing body which has excellent non-combustibility and long term durability by using only inorganic materials such as inorganic foamed pumice, a volcanic product, cement and a radio wave absorbent and a method of manufacturing the radio wave absorbing body using the composition.
SOLUTION: The composition for the radio wave absorbing body consists essentially of inorganic foamed pumice having 0.5-6.2 mm average particle diameter and loose apparent specific gravity of 0.24-0.49, cement and water and if necessary, the radio wave absorbent, the high-performance water reducer and amorphous silica having 0.1-1 μm average particle diameter are added to the composition. Or the composition of the radio wave absorbing body consists essentially of volcanic product having 0.3-10 mm average particle diameter and loose apparent specific gravity of 0.79-1.7, cement and water and if necessary, the radio wave absorbent, the high-performance water reducer and amorphous silica having 0.1-1μm average particle diameter are added to the composition. The method of manufacturing the radio wave absorbing body using the same and a method of applying the radio wave absorbing body are provided.

摘要： PROBLEM TO BE SOLVED: To provide a complex probe device for electromagnetic field evaluation for specifying a spot easily influenced by an external electromagnetic wave efficiently with high resolution, capable of switching accurately and quickly a domain to which an electromagnetic wave is applied, on an electronic circuit board of electronic equipment mounted highly densely.
SOLUTION: Each frame-shaped loop coil 11, 12, 13 having a different size is disposed on the same support 14, to thereby form a loop antenna 1, and the loop opening face of the loop antenna 1 is faced to the electronic circuit board 100, and a specific electromagnetic wave sensitive spot easily influenced by the external electromagnetic wave is detected and evaluated. Hereby, when detecting by switching from an optional frame-shaped loop coil to a smaller frame-shaped loop coil, positioning of the smaller frame-shaped loop coil can be performed accurately and quickly, and a specific electromagnetic wave sensitive spot can be narrowed efficiently, and EMC evaluation can be executed surely and smoothly.
