ABSTRACT
Microwaves are short electromagnetic waves located in the portion of electromagnetic wave spectrum between radio waves and visible light. The energy is delivered in the form of propagating sine waves with an electric field and a magnetic field orthogonal to each other. Microwaves are relatively harmless to humans because they are a form of nonionizing radiation, unlike the much more powerful ionizing radiation (such as X-ray or gamma ray) that can damage the cells of living tissue. Microwaves are used in daily applications such as cooking, radar detection, telecommunications, and so on.
