Microwaves are comprised of electromegnatic waves having wavelenths. These wavelengths are comparatively longer than those of tetrahertz frequensies and shorter for radio waves. The wavelenghts for a microwave range from 30cm with frequency of 1GHz to 1mm with frequency of 300 GHz. A microwave oven is an electrical appliance used in kitchens and for cooking these ovens employ microwave radiation. It was Dr. Percy LeBaron who invented the microwave oven in 1946. The structure of microwave ovens are categorized into following parts,

2. A cavity magnetron
3. A magnetron control circuit
4. A waveguide
5. A cooking chamber.

Microwaves are categorized into different parts depending on different features and brands. Tappan was responsible for providing the world a turn by introducing first microwave model for home use and was named after him.

Tappan microwave range consisted of microwaves that were 24 inch and were operated on 220 volts. Cajun microwave is designed containing a cypress-roasting box capable of cooking large pieces of meat and other items that generally include roast, turkeys, chickens, lambs, beef, deer, and vegetables. Sharp microwaves were generally designed for family, students or a person. Sharp is responsible for bringing innovations in cookery related to microwave, and in speed of microwave cooking. A convection microwave is designed by combining features of a standard microwave and convection oven. These are used for preparing food and not for just heating drinks or frozen food. Microwave convection ovens facilitate users by having features of both microwave and convection. The most important feature it usually provides is fast baking feature. The advantage it owns is roasting food, browning and crisping food, and cooking food quickly as well.
