ELECTROMAGNETIC WAVE ABSORBER USING A DIELECTRIC LOSS SHEET, METHOD FOR FORMING THE ELECTROMAGNETIC WAVE ABSORBER, AND ROTARY BLADE FOR A WIND TURBINE HAVING AN ELECTROMAGNETIC WAVE FUNCTION USING SAME

摘要

Disclosed is an electromagnetic wave absorber using a dielectric loss sheet, a method for forming the electromagnetic wave absorber, and a rotary blade for a wind turbine having an electromagnetic wave function using same. The electromagnetic wave absorber using a dielectric loss sheet comprises: a support layer for ensuring a resonance cavity for electromagnetic waves; a highly conductive backing layer formed on the back surface of the support layer; and a dielectric-loss composite sheet layer which is arranged on the front surface of the support layer, and which has a complex dielectric constant for generating a resonant peak with the electromagnetic wave reflected from the highly conductive backing layer.
