Wireless Charging Using Microwave

In this paper, we have described a mechanism to transfer a low power DC voltage from one mobile to another for the purpose of charging the phone. We have dealt with coupling coils and their resonance. Colpitts Oscillator, Full-Bridge Rectifier and Voltage Regulator circuits have been implemented. This project gives us a new and convenient option of recharging our phones at times when charging from a phone remains the only option because of the lack of having proper charging outlets. This simple idea is a feasible and inexpensive one for mobile

4. Radio: most common form of wireless transmission, typical of home routers and most wireless devices to use this form. Infared uses low frequency light waves to carry data using line-of-sight.

Microwave ovens did not gain widespread popularity in Australia until the early 1980s, although they had been commercially available since the late 1950s. Microwaves revolutionised food preparation - making it possible to defrost, cook or reheat food in very little time, and prompting a growth in the consumption of frozen convenience meals.

On old radios the antenna was detrimental to the radio’s operation. Today, the antenna is not necessary. AM radio does not have as good of quality as FM but it can travel farther distances. FM signals can be interfered by things such as mountains or other barrier

The phone draws energy from a lithium ion battery. Currently, the lithium ion battery has the most energy per volume than any other battery. The lithium ion battery is also a good material to use because of it’s light weight. Another key feature of the lithium ion is its ability to recharge. However, it needs to be recharged properly. The battery needs to be fully charge; if it is overcharged or undercharged significant charging

Microwaves are a fast and easy way of heating things up, but most people don’t know the dangers in microwaves. “Electromagnetic radiation that is foreign to the body, such as microwaves, can disrupt the body’s healthy functioning” (Pitman and Porter Bioresonance Theory of Energetic Healing). “Microwaves are a form of electromagnetic energy, like light waves or radio waves, and occupy a part of the electromagnetic spectrum of power, or energy. Microwaves are very short waves of electromagnetic energy that travel at the speed of light.” (Wayne and Newell). “A microwave distorts and deforms the molecules of whatever food source you put in it” (Why did the Russians Ban an Appliance Found in 90% of American Homes?). The

The Radio was introduced to society because of the telegraph and the telephone. These inventions don’t do the same things but their similar branch of technology. “Radio technology began as “wireless telegraphy”. “It all started with the discovery of radio waves, electromagnetic waves that have the capacity to transmit music, speech, pictures and other data invisibly through air.” [Bellis] Majority of technology uses electromagnetic waves to send data information or TV broadcasts. During the 1860’s, Scottish physicist, James Clerk Maxwell predicted the existence of radio waves; and in 1886, German physicist, Heinrich Rudolph Hertz showed how fast the variation of electric current could be placed into space in the form of

Electromagnetic waves are continually used to upgrade and advance our technology, being implicated for its use in microwave ovens, radio waves for telecommunications and x-rays in medicine.

Most people use microwaves everyday. A lot of people actually wonder how microwaves work. For example, radio waves and radiation, microwaves use radio waves and radiation to heat foods (How Microwave Cooking Works, 2015). Furthermore, radio waves heat food by getting water molecules out of food (How Cooking Works, 2015). In addition, the history of a microwave started off very interesting. For instance, there was someone whose name was Dr.Percy Spencer, he accidently discovered the microwave (Clevenger 2015). More importantly, Dr.Percy had a chocolate bar in his pocket, he was testing a new vacuum and then the radiation and heat from the vacuum melted the chocolate (Clevenger, 2015). In the end, microwaves are something that is very useful

The health of RF-EMFs stared January 1990 when a cell tower was buildup 800 feet from a family that had a dairy farm in Mansfield, Ohio. By the fall, the cattle herb that pastures near the tower was sick, and the children that lived near the tower begin suffering from bizarre skin rashes, that’s when the owner of the farm contacted an environmental protection agency scientist named Carl Blackman. He’s was an expert on the biological effects of radiation from electromagnetic fields (EMFs)-the kind of radiofrequency EMFs (RF-EMFs) by which all wireless technology operates, including not just cell phones towers and cell phones but also Wi-Fi hubs and Wi-Fi –capable computer, smart utility

The military has many uses for electromagnetic waves. They use it in the kitchen all the way to the battlefields. They use radio waves for seeing the damage that space dust could make. They use microwave radiation for cooking. They use Infrared waves for looking for enemies. They also use visible light to send streams of data. Two more waves are X-Rays and gamma rays. X-Rays are used for looking through other objects. Gamma rays are used for explosives.

To make their product compatible in that both XM and Sirius radio can operate on the same frequency.

In the 50's microwaves weren't even thought of. In fact, the only things that used radition similar to that

One of the most life changing technological innovations is the microwave oven. Invented by accident in 1946 by Dr. Percy LeBaron Spencer, the microwave oven was originally received poorly like many other new forms of technology. Fears that the microwave radiation would escape during use, or that it would ruin the art of cooking were some of the worries that many people had when this technology was released (Gallawa, 2007). Through years of refinement however, the microwave oven has become commonplace in kitchens across the globe. While fears of people giving up traditional cooking methods proved to be unfounded, microwaves have proven to be a valuable tool used by everyone from young kids to master chefs. In addition, an entire new food service industry was created based on the ability to quickly prepare food. Frozen foods and microwave popcorn are just a couple of the items we

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking
