Application of Microwave Technology in Various Fields

Written by Ross Clarkson on . Posted in Gadgets, Tech

Microwave technology uses radio waves of various lengths from as long as one meter to as short as one millimeter, which is translated to frequencies between 300 MHz and 300 GHz. The different frequencies are divided into bands that include various lengths and this is what makes them suitable for a certain domain. Believe it or not, the microwaves are being used in more than one fields as you can discover from the following lines.

The prefix “micro” in the name of microwaves is not meant to say that these waves are in the micrometer range but that they are small compared to other waves used in various domains. Starting at the lower boundary of 1 GHz and going up to 100 GHz, these waves are widely used in designing items that surround us whether we are aware of it or not. From the most traditional uses to high-tech devices used in space communication, the microwave technology is one of the most popular, along with the infrared light, the terahertz radiation, or the ultra-high-frequency radio waves.

The medical field

Microwaves are being used in designing various devices used in the medical field for diagnose, imaging, and treatment applications. Thanks to these electromagnetic waves in the microwave regime, doctors are able to detect hidden objects in the human body.

Space communications

A wide array of applications can be found in the communication are where the microwaves are used to enable point-to-point communication on the surface of the Earth, satellite communication, and radio astronomy. The small wavelengths of microwaves allow them to direct the signal in narrow beams without interfering with other devices, which is a common problem in other types of waves.

Navigation and GPS

Microwave Landing System is a precision landing system used in spaceships and aircraft based on microwaves that can block interference with other airports and offer great performance in any weather conditions. Many GPS-based systems rely on microwaves because they have a small footprint and offer great precision.

Food cooking

The most common application of microwaves that we all get into contact with is the food cooking area or the microwave ovens, to be more precise. These appliances use microwaves to break down the food particles and allow for even and precise cooking. While other uses of these waves are far from being accessible, the microwave oven is a popular unit found in most kitchens. The waves used by these devices enable you to cook, defrost, and reheat food in a shorter amount of time than with regular electric or gas ovens. If you take a look at, you will see that modern microwave ovens, can combine microwaves with convection cooking, in order to deliver richly flavored meals, prepared in a short amount of time.
