In 1945, Dr. Perry Spencer, a scientist, was working in a lab when he felt some heat on his hand. The heat was coming from microwaves. These were being emitted from a nearby vacuum tube. Dr. Spencer was curious and place a chocolate bar near the tube. Within seconds, the chocolate melted. That sticky mess was the beginning of a brilliant idea – the microwave!. History of Microwaves.

The Microwave Oven. The first personal microwave was introduced in 1967 by the Amana Corporation. The first microwave for home use was introduced by Tappan in 1955. .. The heating effect of microwaves was discovered accidentally in. circuitry, and relatively low cost make LEDs the preferred lightare biased in the forward direction. Under forward-biased rent. Doubling the forward current approximately doubles 880 nm IREDs standar RODUCTION OF ACROSCOPICALLY RDERED ANOSTRUCTURED AGNETIC UMMARY P RODUCTION OF M ACROSCOPICALLY O RDERED N ANOSTRUCTURED M AGNETIC C OMPOSITES U SING AN I NNOVATIVE D RAWING AND B UNDLING T Abstract: Optoelectronics is the study and. application of electronic devices that source,. detect and control light. Optoelectronics can . be broken down into two sub-divisions; light . emission and light detection. . Microwave Cooking How long have microwaves been around?

 Microwaves:. Microwaves are electromagnetic waves with a frequency with wavelengths ranging from one meter to one millimeter (frequencies between 300 MHz and 300 GHz).. Microwaves are ideal when large areas need to be covered and there are no obstacles in the path..
