Introduction to EMTL Notes

In the past part, we have covered the fundamental numerical apparatuses expected to consider EM fields. We have just referenced in the past part that electric charge is an essential property of issue and charge exist in basic various of electronic charge. Electrostatics can be characterized as the investigation of electric charges very still. Electric fields have their sources in electric charges. ( Note: Almost all genuine electric fields change somewhat with time. Be that as it may, for some issues, the field variety is moderate and the field might be considered as static.

For some other cases, spatial dispersion is almost the same concerning the static case despite the fact that the genuine field may shift with time. Such cases are named as semi-static.) In this part, we first examine two major laws administering the electrostatic fields, viz, (1) Coulomb’s Law and (2) Gauss’ Law. Both of these laws have a test premise. Coulomb’s law is pertinent in discovering electric fields because of any charge dispersion, Gauss’ law is simpler to utilize when the conveyance is even.

FAQs on EMTL Notes

Question 1.
Classification of mediums

Our first application of Maxwell’s equations will be in relation to electromagnetic wave propagation. The existence of EM waves, predicted by Maxwell’s equations, was first investigated by Heinrich Hertz. After several calculations and experiments, Hertz succeeded in generating and detecting radio waves, which are sometimes called Hertzian waves in his honour. In general, waves are a means of transporting energy or information. Typical examples of EM waves include radio waves, TV signals, radar beams, and light rays. All forms of EM energy share three fundamental characteristics: they all travel at high velocity; in travelling, they assume the properties of waves; and they radiate outward from a source, without the benefit of any discernible physical vehicles.

In this chapter, our major goal is to solve Maxwell’s equations and derive EM wave motion in the following media: = 0, = o, µ=µo) Lossless dielectrics ( = 0, = r 0,so, µ= µr µo, or < ) Lossy dielectrics # 0, = r o, µ= µr µo) Good conductors ( =, µ = µr µo, or > ) Where w is the angular frequency of the wave. Case 3, for lossy dielectrics, is the most general case and will be considered first. Once this general case is solved, we simply derive other cases (1,2, and 4) from it as special cases by changing the values of, and µ. However, before we consider wave motion in those different media, it is appropriate that we study the characteristics of waves in general.

Question 2.
State Columb’s law and write the equation for F that exist between two, unlike charges?

Coulomb’s law is an experimental law formulated in 1785 by the French colonel, Charles Augustine de Coulomb. It deals with the force a point charge exerts on another point charge. By a point charge, we mean a charge that is located on a body whose dimensions are much smaller than other relevant dimensions. For example, a collection of electric charges on a pinhead may be regarded as a point charge. Charges are generally measured in coulombs (C).

One coulomb is approximately equivalent to 6 X 1018 electrons; it is a very large unit of charge because one electron charge e = -1.6019 X 10~19C. Coulomb’s law states that the force F between two point charges Q1 and Q2 is: Along the line joining them Directly proportional to the product Q1 Q2 of the charges Inversely proportional to the square of the distance R between them F= (KQ1Q2)/R2 Like charges (charges of the same sign) repel each other while unlike charges attract. The distance R between the charged bodies Q1 and Q2 must be large compared with the linear dimensions of the bodies; that is, Q1 and Q2 must be point charges. Q1 and Q2 must be static (at rest). The signs of Q1and Q2 must be taken into account in eq.

Question 3.
Forces Due To Magnetic Fields

Having considered the basic laws and techniques commonly used in calculating magnetic field B due to current-carrying elements, we are prepared to study the force a magnetic field exerts on charged particles, current elements, and loops. Such a study is important to problems on electrical devices such as ammeters, voltmeters, galvanometers, cyclotrons, plasmas, motors, and magnetohydrodynamic generators. The precise definition of the magnetic field deliberately sidestepped in the previous chapter, will be given here. The concepts of magnetic moments and dipole will also be considered. There are at least three ways in which force due to magnetic fields can be experienced.

The force can be (a) due to moving charged particle in a B field, (b) on a current element in an external B field, or (c) between two current elements A. Force on a Charged Particle the electric force Fe on a stationary or moving electric charge Q in an electric field is given by Coulomb’s experimental law and is related to the electric field intensity E as Fe = QE This shows that if Q is positive, Fe and E have the same direction. A magnetic field can exert force only on a moving charge. From experiments, it is found that the magnetic force Fm experienced by a charge Q moving with a velocity u in a magnetic field B is Fm = QuX B
