- 1009: How do I model materials with gain/losses?
I am using a time-harmonic application mode to solve an electromagnetics problem. If I want to introduce lossy materials, or materials with gain, what are my options?
- 1004: Resolving the Skin Depth
Why do the currents in my metal look strange? How can I get a realistic solution at high frequencies?
- 977: How do I turn an interior boundary into a perfect conductor in my In-Plane TM Waves model?
I am using the In-Plane TM Waves application mode in the RF Module. I would like to embed a perfect electric conductor, but this boundary condition is available only for exterior boundaries. Why is this, and how can I...
- 951: How do I calculate the capacitance matrix of a multiconductor system?
I have set up a model of a number of conductors. How can I compute all the entries of the multiconductor capacitance matrix?
- 916: Electromagnetic coils: multi-turn with fixed total current and skin effect
How can I model a multi-turn current-carrying circular or cylindrical coil with skin effect? How do I specify a fixed total current in each winding while leaving the spatial distribution of the current density free?
- 909: Can COMSOL Multiphysics be used for TEM mode analysis?
Can COMSOL Multiphysics be used for TEM mode analysis?
- 902: Thin film approximation, contact resistance
- 895: Can COMSOL Multiphysics handle left-handed materials?
Can COMSOL Multiphysics handle left-handed materials?
- 881: Electromagnetic coils: Multi-turn without skin effect
How can I model a multi-turn current-carrying coil in the DC and low frequency AC regime when the skin depth is much larger than the cross-section of the windings? Can I change the number of windings in the coil?
- 878: Should I use the RMS, the peak, or the instantaneous value to specify sources for electromagnetic fields?
Should I use the RMS, the peak, or the instantaneous value to specify sources for electromagnetic fields? How can I specify the phase angle?
- 852: How can I model nonlinear magnetic materials?
How can I model nonlinear magnetic materials? How can I introduce an experimental B-H curve?
- 850: Is there an 'open-boundary condition' for electrostatic or magnestatic simulations?
I want to simulate an electrostatic or a magnetostatic problem in free space. How should I set up my simulation domain, and what boundary condition should I use at the exterior boundaries?
- 808: Can I compute the magnetic forces in COMSOL Multiphysics?
Can I compute the magnetic forces in COMSOL Multiphysics?
