An acousto-optic modulator (AOM) is a device which can be used for controlling the power, frequency or spatial direction of a laser beam with an electrical drive signal. It is based on the acousto-optic effect, that is, the modification of the refractive index by the oscillating ... En savoir plus
This is a model of a moving-coil loudspeaker where a lumped parameter analogy represents the behavior of the electrical and mechanical speaker components. The Thiele-Small parameters (small-signal parameters) serve as input to the lumped model, which is represented by an Electric Circuit ... En savoir plus
This tutorial shows how to set up a multi-element objective lens. The chosen lens is the Double Gauss described in 'Modern Lens Design (2nd edition)', by W. Smith, 2005, pg 323. The tutorial demonstrates how to create a geometry sequence using the 'Spherical Lens 3D' part found in the ... En savoir plus
A gearbox is used to transfer power from an engine to its associated wheels or cogs, which can result in radiating noise to the surroundings. This is due to the transmission of undesired lateral and axial forces on the bearings and housing, while transmitting power from one shaft to the ... En savoir plus
Headphones are closely coupled to the ear, and so it is not possible to measure their sensitivity in a classical acoustic free-field setup used for loudspeakers. The measurement requires the use of artificial heads and ears to accurately represent the usage conditions. This model shows ... En savoir plus
A microwave circulator is a multiport device in which a wave incident on Port 1 is coupled only into Port 2; a wave incident on Port 2 is coupled only into Port 3; and so on. Circulators are used to isolate microwave components, for example, to couple a transmitter and a receiver to a ... En savoir plus
This is a 2D model of an anisotropic porous absorbing material. The absorption coefficient alpha are determined as functions of frequency for three different incidence angles. The example uses Periodic Floquet boundary conditions. The model uses two different methods for modeling the ... En savoir plus
Mixed-mode S-parameters describe the responses of a circuit with balanced ports excited and terminated by two types of modes: common and differential modes. They are calculated using a full S-parameter matrix of a four-port network that is composed of four single ended lines. This ... En savoir plus
A Branch Line Coupler (Quadrature 90° Hybrid) is a four-port network device with a 90° phase difference between two coupled ports. The device can be used for a single antenna Transmitter/Receiver system or an I/Q signal splitter/combiner. The objective of this model is to compute the S ... En savoir plus
This tutorial model demonstrates how to use the Combined Inductively/DC Discharge interface to simulate the plasma generated in a pulsed arc. This modeling technique is useful for a large range of industrial applications including cutting, welding, spraying, waste destruction, and ... En savoir plus
