Microwave power transmission (MPT) is one of the applications of microwaves to transmit power from one place to another place without the need for wires. It is the type of the Electromagnetic Radiations‚ one of the wireless energy transfer methods. Introduction: Firstly‚ we will talk about the term Microwaves‚ Microwaves can also be termed as Radio waves having wavelengths ranging from one millimeter to one meter and the frequencies from 300MHz to 300GHz. These are also known as millimeter waves

to buy her a birthday gift.I have two items in my mind.They are an electric oven and digital camera.I saw these two items in an advertisement in the newspaper. The electric oven costs RM520.00.It is very convenient for Mum to bake a cake and biscuits.It also has a multi-purpose function.Other than baking‚the oven can be used for girling chicken and meat.It can also be used to make a toast and even bake fresh bread.The oven is also easy to clean after use. As for the digital camera‚it also costs RM520

Radio waves and Microwaves Radio communications Radio waves are used to broadcast radio or television signals from transmitters‚ which are then converted into electrical signals with an aerial (which is made out of metal to absorb the radio waves) so you can hear and see them. When done so the aerial converts this wave into an electrical signal (because of the electromagnetic waves energy exciting particles in the aerial and causing them to oscillate/vibrate and thus create an electrical current)

transmitting power without using wires i.e.‚ transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. This concept is known as Microwave Power transmission(MPT). We also discussed the technological developments in Wireless Power Transmission (WPT). The advantages‚ disadvantages‚ biological impacts and applications of WPT are also presented. KEY WORDS Microwave Power transmission (MPT)‚ Nikola Tesla‚ Rectenna‚ Solar Power Satellites

Breakdown of the asset. While gas ovens can differ from model to model‚ they operate on similar principles. First lets explain how a typical gas oven operates and which problems may occur. A gas oven ignition system consists of three basic components; the oven controls‚ the igniter and the oven safety valve. In newer models the igniter will be a glow igniter‚ or in ovens that are a few years old‚ an electrical igniter. Old ovens may work with a pilot light igniter. In this breakdown we will

sort of cross- section that could be used as a wave guide or system of conductors for carrying electromagnetic wave‚ is called a wave guide in which the waves are truly guided. (1) FLANGES :- Flange are used to couple sections of wave guide components. These flanges are designed to have not only mechanical strength but also desirable electric characteristics. (2) TWISTED WAVEGUIDE :- If a change in polarization direction is required‚ twisted section may be used. It is also called rotator. (3) WAVE

Microwave Synthesis of 5‚10‚15‚20- Tetraphenylporphyrin Abstract: In this green chemistry experiment of 5‚10‚15‚20-tetraphenylporphyrin was synthesized from benzaldehyde and pyrrole. using microwave irradiation to heat the reactants.‚ The liquid reactants are absorbed on a solid support‚ silica gel‚ which acts as a Lewis acid catalyst to facilitate the reaction. The reaction forms a porphyrinogen‚ which is then oxidized to the porphyrin product by atmospheric oxygen. Column chromatography is performed

when marginal revenue equals marginal cost. Because our costs are sunk we should lower our prices so that we can fill to capacity. 14.4 A manufacturer of microwaves has discovered that male shoppers have little value for microwaves and attribute almost no extra value to an auto-defrost feature. Female shoppers generally value microwaves more than men and attribute greater value to the auto-defrost feature. There is little additional cost to incorporating an auto-defrost feature. Since men and
