Lecture
This lecture covers the design process of a uniform linear antenna using COMSOL Multiphysics. The instructor explains the parameters of the model, defines the antenna's dimensions, assigns velocities, and sets up the domain extension. The lecture also delves into defining variables, drawing the domain of propagation, and creating the perfect image layer. The physics of pressure acoustics, axial symmetry, and boundary conditions are discussed, followed by meshing the domain and studying the frequency domain. The lecture concludes with analyzing the radiation pattern of the antenna at different frequencies and comparing the results with theoretical models.
