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 nonlinear media, in particular, in plasma.

Full-time form

The study discipline "Oscillations and Waves" is based on the cycle of mandatory bachelor's subjects of the relevant specialty, namely: "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.

Lectures, practical classes; independent 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. Final evaluation - - in the form of an exam; the form of the exam is written and oral. In total, you can get from 0 to 40 points for the exam. A condition for achieving a positive grade for a discipline is to obtain at least 60 points, while the exam grade cannot be less than 24 points.
