Title:
FIBER ASSEMBLED FLAT PLATE TYPE RADIO WAVE ABSORBER
Document Type and Number:
Japanese Patent JP2010205956
Kind Code:
A
Abstract:
To obtain high radio wave absorbing performance in vertical incidence, TE polarized wave oblique incidence, and TM polarized wave oblique incidence.
A fiber assembled flat type radio wave absorber comprises a laminate in which a base layer 1 and a surface 2 form a laminate of two impartibly united layers. The base layer 1 is a layer of fiber forming a lower layer of a radio wave absorber, and the majority of the fiber forming the base layer 1 is arrayed in two-dimensional plane directions. The surface layer 2 forms an incidence surface for radio wave and is formed of a layer of fiber containing fiber entwining with the fiber forming the base layer 1 and partially raised in three-dimensional height directions.
