Exploding egg effect
The present example considers an egg in a microwave oven.

In the considered scenario we analyse the effects of heating an egg in microwave oven.
For the purpose of calculating microwave oven resonances the S-Parameters postprocessing is activated. The S-Parameters postprocessing is set from 2.3 GHz to 2.6 GHz with a frequency step of 0.002 GHz.

Reflection coefficient indicating microwave oven resonances.
The minimum reflection in the microwave oven is recognised at 2.356 GHz. In the second step of the analysis, the model is excited with a sinusoidal at the resonant frequency to investigate the power dissipation in the egg. It can be clearly seen that the dissipated power concentrates in the centre of the egg. In the physical experiment, evaporation of water overheated in that area would cause the explosion of the egg - an experience quite memorable to many who tried it.
