How to convert electrical energy to infrared energy or to microwave energy?

To convert to IR, use an IR lamp, aka heat lamp. IR is heat energy.

 To convert to microwave, you need a magnetron and a high voltage power supply, as is found in a microwave oven. 
For the reverse, it is more difficult.
IR energy to electric energy, you could use a special solar array tuned to the IR frequencies. Or with enough heat, you can boil water and pipe that into a turbine that drives a generator.
Microwave energy, you have to capture it in a dish antenna, and then rectify it to DC electricity.
