Microwave Information Technology

This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the.

Microwave information technology.

Microwave ovens are possible because microwaves can be used to transmit thermal energy. Microwave signals propagate in straight lines and are affected very little by the troposphere. Microwave is a line of sight wireless communication technology that uses high frequency beams of radio waves to provide high speed wireless connections that can send and receive voice video and data information. They are crucial to many forms of communication and impact a broad range of industries.

Today s household microwave ovens consist of an electronic device called a cavity magnetron which produces microwave energy a waveguide that guides the energy in the right direction and a metal enclosure which traps that energy until absorbed by food or another material. Microwaves are the principal carriers of high speed data transmissions between stations on earth and also between ground based stations and satellites and space probes. A system of synchronous satellites about 36 000 km above earth is used for international broadband of all kinds of communications e g television and telephone. Radar and satellite communication motivated the development of modern microwave antennas.

Microwave radar became the central technology used in air traffic control maritime navigation anti aircraft defense ballistic missile detection and later many other uses. A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit information between two fixed locations on the earth. The term microwave refers to electromagnetic energy having a frequency higher than 1 gigahertz billions of cycles per second corresponding to wavelength shorter than 30 centimeters. Microwave technology is used for telecommunications the microwave is easily focused into narrower beams than the radio waves its higher frequency allows the broad bandwidth and high data transmission rates.

Microwave links are are widely used for point to point communications because their small wavelength allows conveniently sized antennas to direct them in narrow beams which can be pointed directly at the receiving antenna. A microwave oven colloquially referred to as a microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range.
