EMTM™

Overview

EMTM™ (Effective Medium Theory Materials) is a computer code that calculates the effective permittivity of a material comprising a substrate or matrix that is randomly loaded with general ellipsoidal particles or inclusions.

Applications

EMTM is used on targets that are prolate (fiber-like) and oblate (disk-like) shaped ellipsoids as well as spheres for 1D RCS prediction.

Benefits

• EMTM is capable of handling both lossy matrix materials and lossy particles.
• EMTM allows the user to choose various distributions for particle shape such as simple, flat, or Gaussian.
• It automatically checks the validity of the theory used for each case after all data are input.

Product Features

• Controlled dispersion of particles
• Prolates (fiber-like), oblates (disk-like) ellipsoids, multi-layered spheres
• Maxwell-Garnet theory
• Relates external field to internal w/ perturbations caused by inclusions
• Various distributions options
• Simple distribution
• Flat distribution
• Gaussian distribution
