    Solve Math Simulation for Laser Microphones

    I have been trying to write the mathematical simulation for this device but unfortunately I found no clue to start with . the simulation should be starting with the Gaussian beam equation of the laser source and then the vibrations in the glass pane cause the window to flex, changing the...

    Semiconductor Diodes: Calculating Rf and Why VD=0

    Semiconductor dioedes ! when proving that the ideal diode is short circuit in forward biasing we calculate the diode Resistance Rf which is equal to the diode forward voltage upon it's forward current ...but why we put VD=0 why?
