Nodes of different colours represent the following:
Solid arrows point from one derived type to another which extends (inherits from) it. Dashed arrows point from a derived type to another type containing it as a components, with a label listing the name(s) of said component(s). Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.
This field is produced by 2 charged plates of opposite charge.

Let an infinitely thin plate of charge density \( \sigma \) which is finite in \( \vec{e}_x \) direction but not in \( \vec{e}_y \), cf. modules/environment/field/plate_field.tex. This plate creates an electric field at \( (x, z) \) of expression: \[ \vec{E}(x, z) = \frac{1}{4\pi \epsilon_0} \sigma \vec{b}(x, z) \] where \( \vec{b}(x, z) \) is defined in plate_expression.
