Microwave OvenMicrowave cooking is not the same as the cooking method used by a conventional oven, and this goes even more for microwaves with convection technology. This type of oven utilizes radio wave to penetrate the food and convection means that the air is pushed around the microwave. It excites the water and fat molecules in the food to cook it evenly and unlike conventional oven, the heat doesn’t migrate through the use of conduction.

When you turn this oven on, there will be heat everywhere as the result of the molecules being triggered. However, microwaving does have some limitations. For instance, when you cook thick pieces of food, the heat doesn’t penetrate evenly. This is because it doesn’t conduct heat, rather it excites the atom.
