Title:
λ／４型電波吸収体
Document Type and Number:
Japanese Patent JP6789437
Kind Code:
B2
Abstract:
An object is to provide a λ/4 radio wave absorber that includes a support, a resistive film, a dielectric layer, and a reflective layer, and that has higher radio wave absorption performance. The object is achieved by a λ/4 radio wave absorber that includes a support, a resistive film, a dielectric layer, and a reflective layer, and that satisfies formula (1): -0.375x + 1086.9 < y < -0.375x + 1140 wherein x represents a resistance value of the resistive film, and y = the thickness of the support × (the relative permittivity of the support)0.5 + the thickness of the dielectric layer × (the relative permittivity of the dielectric layer)0.5.
