The student should know free and forced linear oscillations systems; fluctuations of parametric systems; free and forced oscillations of nonlinear oscillators; quasi-harmonic, relaxation and stochastic self-oscillations; coupled oscillations; propagation and radiation of linear waves; interaction of waves of various types, including in open systems; parametric interaction of waves; solitons and shock waves; regular and stochastic autowaves. The student should be able to calculate the properties of free and forced oscillations in linear systems; calculate the properties of free and forced oscillations in parametric, nonlinear and self-oscillating systems; calculate the properties of waves in linear and non-linear media.

Full-time form

The educational discipline is based on the cycle of disciplines "Mathematical analysis", "Differential equations", "Methods of mathematical physics", "General physics", "Radio circuits and signals", "Radio electronics", "Theoretical mechanics". Prerequisites: the student must know: basic laws, equations and relationships of mechanics, molecular physics, electricity and magnetism; the student must be able to: use the apparatus of higher mathematics (mathematical analysis, linear algebra, differential equations).

The study of the discipline "Oscillations and waves" allows us to understand the essence of such phenomena: free and forced oscillations of linear systems; fluctuations of parametric systems; free and forced oscillations of nonlinear oscillators; quasi-harmonic, relaxation and stochastic self-oscillations; propagation and radiation of linear waves; interaction of waves of various types, including open systems; parametric interaction of waves; solitons and shock waves.

Lecture classes, practical classes, colloquium, independent individual work.

Semester assessment: the academic semester has three content modules. After completing their studies, colloquiums and written modular tests are held. Mandatory for admission to the exam is: obtaining at least 36 points of the semester rating. The final evaluation is in the form of an exam, the form of the exam is written and oral. The condition of achieving a positive assessment for discipline is to receive at least 60 points, the exam grade cannot be less than 24 points.
