Introduction
Results
Heat source can be seen everywhere in nature. It is such a commonplace that we are almost unaware of how difficult it is to control heat flow. Fortunately, with the method of coordinate transformation, we have designed lots of illusion devices to achieve the goal: controlling the heat flow.

FIG 3. Different thermal patterns
The equation of heat conduction:
FIG 1. Schematic diagram of coordinate transformation
FIG 4. Thermal rectifier : expand and shrink
With the coordinate transformation:
Conclusion
Then we get the parameter:
Varieties of illusion devices are shown in this poster which will have broad application prospect.
