  • Patent number: 8219332
    Abstract: Electromagnetic field distribution is measured by considering time variations of a measured electric and/or magnetic field value. In response to scanning performed with a probe at an arbitrary set of measurement coordinates in a predetermined measurement plane in the vicinity of an object to be measured, a signal is detected at each of plural sets of coordinates in a measurement plane. Electric and magnetic fields are computed during a measurement time period at each set of measurement coordinates in the measurement plane based on measurement coordinates where the probe is positioned and the signal is detected with the probe. Amplitude probability distribution during the time period at each set of measurement coordinates in the vicinity of the object is computed based on the computed intensity, then mapped and displayed.

  • Patent number: 7589661
    Abstract: A radio wave absorber that can be bonded securely to a flexible cable or a flexible printed circuit board eliminates the need for a release film. A radio wave absorber comprising a thermosetting adhesive sheet 1 that is cured into a flexible material, and a Sendust-containing curable resin composition layer 2 that is cured into a flexible material, wherein the curable resin composition layer is formed on either surface of the thermosetting adhesive sheet. The average particle diameter of Sendust is in the range of 30 to 100 ?m. The content ratio of Sendust in the curable resin composition layer is in the range of 50 to 85 wt %.

  • Publication number: 20080292891
    Abstract: An electromagnetic wave shielding sheet having a high shielding effect for electromagnetic waves and capable of suppressing secondary emission causing noises without using GND connection, in which the electromagnetic shielding sheet includes a laminate film on a paper substrate, the laminate film has a laminate structure where an adhesive layer having adhesion property, a resistor layer and an insulator are laminated, the resistivity of the insulator is set to about 106 ?/cm or higher and the resistance value of the resistor layer is set to about 10? to 300?, so that secondary emission can be decreased while keeping a high shielding effect.
