The present invention disclosed herein relates to an electromagnetic interference measuring device and an electromagnetic interference measuring method. More particularly, the present invention relates to an electromagnetic interference measuring device that is related to a carbon nano tube.
Electromagnetic interference (EMI) indicates an electrical or electromagnetic interaction that occurs when devices including an electronic circuit are close to one another. In order to perform a stable operation, the device including an electronic circuit should not be affected by an external device and nor affect the external device. This is called electromagnetic compatibility (EMC) of a device.
An electromagnetic shielding material may be used to prevent electromagnetic interference. A carbon nano tube (CNT) is a material that has been mainly studied as the electromagnetic shield material, recently. The CNT has high conductivity and thus a good electromagnetic shielding property. The EMI of the CNT may be measured to verify the electromagnetic shielding property of the CNT. The EMI may be measured by using an electromagnetic wave that is generated from the CNT in response to an electromagnetic wave applied to the CNT.
