This simulation demonstrates the working of an Amplitude Modulation (AM) circuit using operational amplifiers. In this setup, a high-frequency carrier signal of around 100 kHz is combined with a low-frequency modulating signal to produce an amplitude-modulated output. The circuit consists of two op-amps, resistors, and signal sources arranged to mix and control the amplitude variations effectively. The oscilloscope display shows the modulated waveform in green, while the red outline represents t

Light has orbital angular momentum (OAM). You can model an OAM beam with COMSOL Multiphysics version 5.5 and the add-on Wave Optics Module. In this OAM beam tutorial, learn how to simulate Gaussian to Laguerre Gaussian beam shaping: https://buff.ly/39awekW | COMSOL Multiphysics
