Microwave heating theory

Web12 okt. 2024 · Cooking Principle : a). The microwaves generated by the magnetron reflected cavity and are distributed uniformly as the food rotates on the turntable. The food is thus cooked evenly. b). The microwaves are absorbed by the food upto a depth of about 1 inch (2.5 cm). Cooking then continues as the heat is dissipated within the food. WebThe readers will gain knowledge on how Microwave signals are generated, controlled, transmitted, and measured. Prerequisites It is a simple tutorial written in a lucid way. We believe almost any reader having a basic knowledge of analog and digital communication can use this tutorial to good effect. Previous Page Print Page Next Page Advertisements
