Wavexorb Dielectric Foam Absorbers are lightweight, conductive carbon loaded materials which provide high levels of loss at all angles of incidence. Dielectric Foam Absorbers are effective in free space applications such as radomes or antennae.
What is low-loss dielectric?
The material chosen for the buffer layer is a dielectric such as PTFE, polypropylene, silicone, or polyamide. These materials all have low dielectric loss in common, which prevents them from heating in the RF field. These dielectrics also tend to have high breakdown voltage limits as well.

Is polyurethane RF transparent?
This series of machinable, closed cell polyurethane foams provide an RF-transparent, low-loss protective layer for applications requiring optimal performance where electrical insulative materials are needed.
Is foam a good dielectric?
Many polyurethane foams offer a wide variety of physical properties, as well as desirable dielectric properties for applications requiring minimal dielectric constant and loss tangent. ... Polyurethane foam is subsequently used in a myriad of industries such as aerospace, medical, construction, marine, and composite core.Nov 3, 2015
2 Measurement Methods. Measurement of dielectric properties involves measurements of the complex relative permittivity (εr) and complex relative permeability (r) of the materials. A complex dielectric permittivity consists of a real part and an imaginary part.
What is dielectric FOAM?
Wavexorb Dielectric Foam Absorbers are lightweight, conductive carbon loaded materials which provide high levels of loss at all angles of incidence. Dielectric Foam Absorbers are effective in free space applications such as radomes or antennae.
What is the best material for a radome?
In all radome applications, polyurethane foams offer an effective solution for cost effective materials that are both versatile and robust. Easily optimized material allows for high performance with low dielectric interference.
