User libraries is a sub-package where useful Python modules contributed by users are stored.
The module is intended to provide a database of electromagnetic properties of different materials. It currently includes the following material libraries:
How to use the module¶
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 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.
