Microwave heating refers the use of electromagnetic waves ranges from 0.01m to 1m wave length of certain frequency to generate heat in the material. These microwaves lie in the region of the electromagnetic spectrum between millimeter wave and radio wave i.e. between I.R and radio wave. Microwave, which has gained recent popularity, has a great potential in pharmaceutical industry. Waves are generally of two types Electromagnetic waves and Mechanical waves. The main point of differentiation is electromagnetic waves do not require a medium for transportation, as required by mechanical waves.1, 2 Microwave is generated in special type of electron tubes. These contain cathode, anode and grid inside an evacuated envelope. For generation of microwaves these should operate at very high frequency range (300 - 3000 MHz). Ordinary electron tubes can operate at frequencies up to about 30 MHz. So the tubes must be designed in a different manner, because the frequency is comparable to the electron transit time (it is the time needed for electrons to travel between electrodes). 3.4.5 Microwave is a type of electromagnetic wave whose wavelength range falls in between Radio waves & Infrared waves as shown in Table
