Module goal - Knowledge and skill to be achieved by students |
|
| Course objective is to give students characteristic knowledge in fields and propagations, and to be stimulation for understanding fundamentals and for analysis of physical effects in electrical engineering. <br> An emphasis is put on aspects of engineering applications of theoretical results: understanding how principles of electromagnetics can be applied on formulating and solving engineering problems. <br> Considerations of electromagnetic effects are based on Maxwell equations, on macroscopical level, which gives simplicity and explicitness. |

Didactic methods |
|
| Course is realised through lectures done by a teacher; in the end of every subject aspects of characteristic applications are shown. Projects which students do individually or in groups are structural part of the course. <br> Experimental segment (laboratory) is consisted of specific phenomena demonstrations, on real models and in simulations. <br> |
|
Exams |
|
| Through the course, student gains points according to following system. <br> Attendance to lectures and auditory hours: student which misses lectures and auditory exercises more than three times cannot get teacher's signature for ratification. Students are obligated to attend all laboratory hours. <br> Homework and project assignments: maximum 20 points. <br> Partial exams: two partial exams, each worth 20 points. <br> Partial exam lasts for 90 minutes. <br> Student which in the end of the course has less than 20 points has to take the course again. Student which in the end of the course has more than 40 points takes final verbal examination, which is worth maximum 40 points. To pass the course, on final verbal examination student has to make minimum 20 points. Student, who does not get minimum 20 points, takes corrective verbal examination. Student which in the end of the course has more than 20 but less than 40 points takes corrective examination. Corrective examination is valued in the following way: <br> - written examination, worth maximum 30 points. <br> - verbal examination, worth maximum 40 points. <br> Student can take verbal corrective examination only if after passing written examination has made total score of 40 or more points; this score is made of points gained through: attendance, homework, project assignments, passing partial exams and passing written corrective examination. Verbal corrective examination is worth maximum 40 points. To pass the course, on verbal corrective examination student has to make minimum 20 points. Student, who does not get minimum 20 points, takes the course again. <br> |
