This example explores the shift in natural frequencies caused by changing the temperature. One study investigates a doubly clamped beam where both ends are fixed, while the other study looks at a cantilever beam where only one end is fixed. The following effects are studied: Stress ... 詳細を見る
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 ... 詳細を見る
This tutorial shows how to solve the full time-dependent wave equation in dispersive media such as plasmas and semiconductors. The 2D TM in-plane wave model solves for the vector potential from the wave equation and for an auxiliary electric polarization density from an ordinary ... 詳細を見る
This tutorial model solves the Gross–Pitaevskii Equation for the ground state of a Bose–Einstein condensate in a harmonic trap, using the Schrödinger Equation interface in the Semiconductor Module. The equation is essentially a nonlinear single-particle Schrödinger Equation, with a ... 詳細を見る
The Hubble Space Telescope (HST) is an example of a standard Cassegrain telescope. The Conic Mirror On Axis 3D part from the COMSOL part library is used to construct the HST Ritchey-Chretien geometry. Multiple release features are used to generate on and off-axis ray and spot diagrams. 詳細を見る

An evanescent-mode cavity filter is resonant at a frequency lower than its original fundamental mode frequency. Evanescent mode resonance can be realized by creating a discontinuity or reactance inside the cavity. The basic model was modified by the addition of a metal box at either end ... 詳細を見る
A fractal is a mathematical form showing self-repeating patterns. By virtue of its geometrical properties, a fractal structure can generate multiple resonances in RF applications. This antenna model uses a 3rd order Sierpinski triangle and the calculated S-parameters shows good input ... 詳細を見る
This model demonstrates the use of optical tracing for studying optically large gradient-index structures with anisotropic optical properties. Additionally, the model introduces a smoothing technique for handling discontinuities of refractive index on curved surfaces, which are typical ... 詳細を見る
