S-Parameter Method, Free Space Type
Dielectric Constant, Dielectric Loss Tangent, Permeability, Transmission attenuation, Electric wave absorption rate
Millimeter wave / Microwave Measurement System
(Dk, Df/ ε′r, tanδ/ μ′r, μ"r)

Model No. DPS24
Suitable for measuring higher loss materials like electric wave absorbers !!

This is a free-space type measurement system that can simultaneously measure relative permittivity, dielectric tangent, and magnetic permeability.

It can use TRL and LRL calibration and is suitable for measurement of materials with high loss.

For measurement of low-loss materials, we recommend;

Dielectric Constant and loss tangent Magnetic Permiability

Calculation
software (Windows)
S-parameter transmission mode programm DMP-03
Multilayer plate Simulation software for making designs of emblem and radome Can simulate transmission attenuation amount of multilayer plate (max. 4layers) by using permittivity (εr' ) and permeability (μr') . And Can set angles of incidence, TM and TE wave. It is optimal simulation software for making designs of emblems. SFW05
Single Layer Type / Multi-layer Type, Electric Wave Absorber, Return Loss Simulation Software This is the best simulation software to make designs of wave absorber for far field. EAS01
