This **MATLAB** tool is a complete implementation of the **magnetic mirroring method** also known as **method of images**.

The complete implementation is **object oriented** and includes several **examples**.

The tool be used to compute the magnetic properties of different components, e.g., **inductors, transformers, and litz wires**.

The following properties can be computed:

* **Magnetic field pattern** (vector or norm)

* **Inductance matrix** between the conductors

* **Energy** for a given excitation

 

The following configurations can be computed:

* Conductors in free space (no magnetic boundary)

* Conductors surrounded by a single magnetic boundary

* Conductors surrounded by two parallel magnetic boundaries

* Conductors surrounded by a box of four magnetic boundaries

The following additional features and constraints exist:

* The magnetic boundary can feature finite permeability

* The conductors are accepted to be round with an uniform current density

* The conductors are accepted to be round with an uniform current density.

* The radius and the position of the different conductors is arbitrary

* Line conductors (without zero radius) are accepted

* No HF effects (skin or proximity) are considered (can be added in post-processing)

This tool is developed by the **Power Electronic Systems Laboratory at ETH Zurich** and is available under the **BSD License**. The code is also available on the ETH Data Archive.

## Examples

The following examples are included:

* [test_inductor.m](test_inductor.m) - Simulation of an inductor with air gaps

* [test_transformer.m](test_transformer.m) - Simulation of a transformer

* [test_litz.m](test_litz.m) - Current sharing problem for untwisted litz wires

## Compatibility

The tool is tested with the following MATLAB setup:

* Tested with MATLAB R2018b or 2019a

* No toolboxes are required.

* Compatibility with GNU Octave not tested but probably easy to achieve.
