Course description
In modern medical technology, various wave phenomena such as sound waves, radio waves, and light are used. In this lecture, the goal is to learn the fundamentals of wave phenomena in various physical systems. First, the concept of the reference mode of vibration and the superposition of the modes will be described for a mechanical spring model. Next, we extend to the continuum and explain the introduction of the wave equation, the properties of the waves, and the Fourier transform. In this lecture, classes and exercises will be conducted while introducing the relationship between vibration and wave phenomena and biomedical engineering.
Expected Learning
The achievement criteria are described below.
(1) To be able to explain the normal mode of vibration, dispersion relation, and wave properties.
(2) To be able to perform analysis using Fourier series expansion and Fourier transform.
(3) To be able to explain mechanical waves (sound waves) in a continuum.
(4) To be able to explain electromagnetic waves (radio waves and light).
