Webb15 jan. 2024 · Infrared waves are the electromagnetic waves having frequency range from 300 GHz to 400 THz. The wave length if infrared is 750 nm to 1 mm. Characteristics of Infrared: It supports high bandwidth, and hence the data rate will be very high. Infrared wave can not penetrate through wall or hard object. Thus it is limited in indoor use. WebbIn summary, it is important to point out that for microwave heating both properties ε′ and ε″ are a function of microwave frequency [36]. Whereas the dielectric constant shows a decrease from 1 to 20 GHz, the loss factor shows an increase from 1 to 10–12 GHz followed by a decrease at higher frequencies.
