Microwaves
By: Karsen Barnett
Microwaves can be used to.....
- Communicate with satellites in orbit
- Find weather issues using radar
- Study the universe
- Or even to cook popcorn
Electromagnetic Spectrum: Microwaves
In the video above you will learn about what a microwave is, how they are used, and what they can do.

The use of radar to keep an "eye" on the "eye"
Microwave Background
Discovered in 1960 by a pair of scientists at Bell university. Is a picture of the never-ending cosmic noise. The picture was found by COBE (Cosmic Background Explorer)

Microwaves are good at breaking through haze, light rain, snow, clouds, and smoke making them great uses for studying earth from a satellite.
Radar Tower
Microwaves are good at transmitting information because they can travel throuhg tough places that other waves cannot.
Microwaving Soup
Obviously microwaves can be used to microwave food because the heat from the waves travelling around inside the microwave oven.
Microwave Range
The frequency range of the Microwave as shown above is from 0.5-30GHz. While the wavelength range is as long as one meter to as short as one millimeter
Microwave Tomograph
The Microwave Tomograph is a new form of radiation therapy for cancer. It uses 30 antennas that act as both transmitters and receivers. As says, "The antennas transmit microwaves with high efficiency, perfectly synchronised to heat up individual tumours. The process can be likened to creating a tidal wave in the region of the tumour while the surrounding sea remains calm." In other words, the microwaves send out heat blasts that are focused on the tumor cells and individually fight these cells keeping the rest of the cells alive. Leaving the good cells alive while the bad cells are burned up. As well as kill cells the antennae do one more job. They can receive signals given off by the radiation to actually find the malignant tissue. The antennae are some of the most important parts of the microwave tomograph.
Materials
In the creation of the Microwave Tomograph many different materials are involved. First is the ring or the helmet. The ring acts as a containment unit t make sure that the microwave radiation does not escape. Next is the antennae the antennae serve as a pathway for the radiation to travel along. After that is the computer, the computer acts as the control center so to speak. From the computer you can see what is happening and you control the radiation. Lastly is the chair, now you may think it i unimportant but research proves otherwise. Could you sleep upright?
Microwave Tomograph Neck Cancer
The ring is full of antenna that will kill off all malignant cells while not touching the healthy cells.
Microwave Tomograph Brain Cancer
The antenna inside of the helmet are set to be precise and deadly to all cancer cells. The wires coming out of the back of the helmet are used to send the results to a computer hooked to the helmet.
Microwave Tomograph equipment
The "stuff" shown above is the equipment needed to do the tomograph treatment.
Who, When, Its Impact and What is it made of ?
1. This technology was introduced to the world in 2011 by the Chalmers Team.
2. This technology has impacted our society by giving us a new alternative to regular cancer treatments that are often quite deadly. Now there is a much slimmer chance of death or injury and a much higher chance of success and healing.
3. This technological advancement's make up has not yet been documented, but we do know that the Chalmers Team's Invention uses about 0.5-3GHz of power to generate the results they need.
