Title:
NOISE SUPPRESSOR USING DIELECTRIC CHARACTERISTIC
Document Type and Number:
Japanese Patent JP2009177002
Kind Code:
A
Abstract:
To provide a noise suppressor which is lighter in weight, thinner, and can exert a higher noise suppression effect than a conventional noise suppressor using a magnetic material.
The noise suppressor uses dielectric characteristics and satisfies a formula (1) r't300 (mm) and a formula (2) r''t3 (mm), wherein t (mm) is a thickness of the noise suppressor, r' is a real part of a complex dielectric constant of the noise suppressor, and r'' is an imaginary part of the complex dielectric constant.
