A gate-all-around MOSFET consists of a nanowire with a gate electrode wrapped around the circumference. Since the entire nanowire forms the channel, this configuration provides the best possible electrostatic control of the channel and offers a good candidate for the miniaturization of ... Mehr lesen
The model compare the electromagnetic force calculated by virtual work and maxwell stress tensor methods on the axial magnetic bearing. The forces is evaluated by studying the effect of a small displacement on the electromagnetic energy of the system. This is done by using the Magnetic ... Mehr lesen
Optical computing has been a promising paradigm alternative to the current electronic computers. This model simulates an optical 4-by-4 unitary matrix multiplication device based on a network of six Mach–Zehnder interferometers (MZIs). A more detailed description of this model can be ... Mehr lesen
A 3D silicon waveguide is set up with rib and slot configurations. The meshing includes physics-controlled mesh, with the number of longitudinal mesh elements set to 50 to visualize the wave oscillation. The detailed discussion of the model setup is discussed in the blog post: "Silicon ... Mehr lesen
This tutorial studies the deposition of amorphous silicon using an inductively coupled plasma reactor with a silane/argon gas mixture. It examines how the deposition rate varies across the wafer as a function of silane mole fraction and input power. Mehr lesen
In mode analysis it is usually the primary goal to find a propagation constant. This quantity is often, but not always, real valued; if the analysis involves some lossy part, such as a nonzero conductivity or an open boundary, the eigenvalue is complex. In such situations, the real and ... Mehr lesen
Microstrip filters can be fabricated directly on a printed circuit board (PCB) with a microstrip line going from the input to the output. Along the microstrip line there are a number of stubs of certain lengths and widths. The design of the filter involves choosing the impedance of the ... Mehr lesen
This example demonstrates how to set up a spatially varying dielectric distribution. Here, a convex lens shape is defined via a known deformation of a rectangular domain. The dielectric distribution is defined on the undeformed, original rectangular domain and is mapped onto the deformed ... Mehr lesen
This tutorial model explores the behavior of a microwave plasma torch. The plasma is generated within a dielectric tube inserted in a rectangular waveguide. The simulation solves the coupled equations for plasma transport and heating, microwave electromagnetic fields, fluid flow, and ... Mehr lesen
This example demonstrates how to compute transmission line parameters such as series resistance, series inductance, shunt conductance, and shunt capacitance per unit length using the predefined Transmission Line RLGC Parameters multiphysics interface. The demonstration also includes the ... Mehr lesen
