Electro-Magnetic Wave Propagation for the course Propagation and Antennas - Research account ExampleThis paper discuss the properties of casts during propagation. I. Introduction Electro magnetic radiation otherwise abbreviated as EMR refers to forms of competency which are produced by oscillating magnetic and electric disturbances or by expungement of electrically charged particles travelling through matter or a vacuum 1. Electromagnetic Radiation is in the forms of waves. These waves accept Radio Waves, Microwaves, Infrared, X- rays and Gamma-rays 1. The magnetic and electric palm resulting in the electromagnetic waves interact by coming unneurotic at right angles to each other and these combined waves move perpendicular to both electric and magnetic oscillating fields and as a result, the disturbance is caused 2. The resulting electron radiation is released in bundles of light efficiency which travel at a step on it of 299792458 m / s, equivalent to the speed of light, a s quantized openhearted waves. These electromagnetic waves are grouped according to their wavelength and these results in the electromagnetic spectrum 3. The resultant magnetic and electric waves move perpendicularly to each other having certain characteristics which are Amplitude, frequency and wavelength 2. From the origin of the electromagnetic wave, it is propagated extinctwards in all directions however depending on the type of fair in which it is travelling 2. For instance if its air, the wave spreads out in a uniform manner in all directions in the medium 4. After the wave has moved far from its origin, the wave is considered to have spread enough and it appears as though it has it has the corresponding premium everywhere which is perpendicular to its direction of flow 4. And this results in a plane wave. The electromagnetic waves speed is equivalent to light speed in a vacuum. When the waves travel in other medium such as water air, and glass, the speed is slower as com pared to that in a vacuum 4. Characteristics of these electromagnetic waves during propagation include II. Interference This is the process in which two waves superposes to form one resultant wave. For affray to occur, the source of the waves must be coherent 5. If two electromagnetic waves having the same frequency get together i.e. they superpose, it results into a wave which has the resultant magnetic and electric field strength equal to the sum of fields of the two waves 5. When two strong waves moving that have their fields moving in one direction, i.e. same direction in time and space, the resulting waveform is twice that of each individual waveform. This results in constructive interference. However, the principle of superposition of a wave having an electric field in one direction in space and with other electromagnetic radiation wave which has the same frequency but with an electric field in the contrary direction in space and time results in cancellation and a result, there is no formation of a waveform 6. This implies that the two waves are not in phase. The resultant effect is termed as destructive interference. In summary, superposition of waves results in destructive, constructive or partial interference considering the magnitude of the waves world superposed 1. III. Reflection During the transit of electromagnetic wave from one medium into another, and the two media having different refractive index, the speed of the wave changes the transmitted is made to change
