A

90-100

Excellent

Utmärkt

Have an excellent understanding of the topics listed below (the student should be able to solve almost any problem in these areas -within the scope of the course- and understand both the physics and the mathematics involved very well):

• applications of vector calculus to the study of electrodynamics

• use of Green functions and expansions in orthogonal functions to study electrostatics problems with boundary conditions

• multipole expansion of electrostatic fields and fileds in dielectric media

• continuity equation and magnetostatics

• Maxwell's equations and some of their solutions including retarded and advanced Green functions, Jefimenko's equations, radiation fields in different zones, effect of surface charges and currents, reflection and refraction of em waves

• energetics of electric and magnetic fields and the energy conservation law

• the 4-vector formulation of special relativity and the Lorentz covariant formulation of electrodynamics

B

80-89

Very good

Mycket bra

Have a very good understanding of the topics listed above for grade A: (the student should be able to solve most problems in these areas -within the scope of the course- and understand very well the physics and mathematics involved, except for the most advanced problems that may require original thinking. In the latter case, the student should have at least some idea of the physics or mathematics input required to solve the problem even though he/she cannot come up with the complete solution)

C

70-79

Good

Bra

Have a good understanding of the topics listed above for grade A: (the student should be able to solve problems in these areas -within the scope of the course- and understand very well the physics and mathematics involved, except for the most advanced and moderately advanced problems that may require original thinking or somewhat sophisticated analysis. In the latter case, the student should have at least some idea of the physics input required to solve the problem even though he/she cannot come up with the complete solution)

D

60-69

Satisfactory

• applications of vector calculus to the study of electrodynamics

• use of Green functions and expansions in orthogonal functions to study electrostatics problems with boundary conditions

• dipole and quadrupole fields and electric fileds in dielectric media
