Main Applications

Knowledge of the RF and microwave properties of materials is crucial to properly design and utilize a component or system to be used in the radar and telecommunications domains. It is also crucial to understand the propagation of EM waves in complex media (soil and man-made structures etc.). The key parameters that need to be evaluated are the complex dielectric constant (i.e. permittivity) and conductivity, though for certain applications other parameters could also be of interest such as:

  • Permeability
  • Transfer impedance
  • Shielding effectiveness
  • Reflectivity (i.e. backscattering)

Most of these parameters relate not only to a simple material test (i.e. bulk property of the material), but also to an item made out of the material itself, resulting in the need for RCS or EMC/EMI tests.

IDS provides services for the assessment of material properties in terms of backscattering, shielding effectiveness and bulk properties (i.e. complex permittivity) for a wide range of materials (e.g. solids, liquids, granular, mixtures, dielectric, conductive, nano-materials and meta-materials) and frequencies. The possible test frequencies start at a few kHz and go up to 50 GHz.
