User libraries is a sub-package where useful Python modules contributed by users are stored.

Materials

Information

The module is intended to provide a database of electromagnetic properties of different materials. It currently includes the following material libraries:

  • eccosorb.txt contains information on some of the Eccosorb LS series of electromagnetic absorber materials manufactured by Laird NV (formerly Emerson & Cuming Microwave Products NV). LS 14, 16, 18, 20, 22, 26, 28, and 30 are included. They are simulated using a 3-pole Debye model.

How to use the module

Example

The simplest way to access any of the material libraries is to use the #include_file command, after which the name of the material can then be used with any object construction command:

#include_file: user_libs/materials/eccosorb.txt
#box: 0 0 0 0.5 0.5 0.5 eccosorb_ls22

Eccosorb

Eccosorb are electromagnetic absorber materials manufactured by Laird NV (formerly Emerson & Cuming Microwave Products NV). Currently models for some of the LS series (14, 16, 18, 20, 22, 26, 28, and 30) are included in this library. The models were created by fitting a 3-pole Debye model to the real and imaginary parts of the relative permittivity taken from the manufacturers datasheet. The following figures show the fitting.
