45th 2D example -rectangular waveform for oscillating voltages.

See the general note on time-dependence, and the examples test2d08 (sinusoidal), test2d24 (user-supplied) and test3d08 (sinusoidal).

Similar to test2d08 but with a rectangular instead of sinusoidal waveform.

The voltage goes from

V0 at time 0

to V0 + V1 at time T1

to V0 + V2 at time T2

to V0 + V3 at time T3

to V0 + V4 at time T4

to V0 at time T5.

For the data entered above, the voltage therefore goes

from 0 to 19 at time 0,

stays at 19 until time 5e-7ms,

then changes to -19,

stays at -19 until time 1e-6ms,

when it reverts to 0.

This cycle repeats every 1e-6ms.

The waveform is displaced by t0 = 1e-6ms.

The printing level is 'f', which corresponds to 'all + fields' (See Help), and so the 2 components of the electric field appear in the information box and the output file -which enables the rectangular waveform to be confirmed.

The mesh method ('m') is used for ray tracing. The second and later rays are therefore traced much more quickly than the first ray.
