I want to create an effect of a rotating electric field by applying time-varying voltage on electrodes. My electrodes are circular but divided into 4 quadrants, such that in each quadrant the voltage is shifted by a phase difference of 90 degrees. I see that the ES-PIC solver only allows to set static voltages. Is there any way to put the RF bias on top of the DC voltage?
As per update in September 2021, CST ES-PIC (Particle-in-Cell) solver is a numerical simulation tool used for modeling charged particle dynamics in electromagnetic fields. To apply an RF (Radio Frequency) voltage on an electrode in CST ES-PIC, you typically follow these steps:
- Create the geometry of your electrode(s) within the CST Studio Suite environment. This is usually done using the 3D modeling tools provided by CST Studio Suite.
- After creating the geometry, generate an appropriate mesh for your model. A fine mesh is often necessary around the electrode(s) and in regions where significant particle interactions are expected.
- Define the relevant material properties for the electrode(s) and the surrounding medium. Ensure that you have appropriate conductivity and other electrical properties set for the electrode material.
- In CST ES-PIC, you typically define boundary conditions using Ports and Loads. To apply an RF voltage on an electrode, you need to define a Port or Load that represents the RF source.
- To apply an RF voltage to an electrode, you'll need to create a Port representing the RF source. In CST Studio Suite, you can create a port by going to the "Excitations" tab and selecting "Port."
- Within the Port properties, you can specify the frequency, amplitude, and phase of the RF voltage source. You can choose between various waveforms like sinusoidal, square wave, etc.
- Once you have defined the Port representing the RF source, you can assign it to the appropriate electrode(s) by selecting the electrode(s) in the model and assigning the Port as an excitation.
- Define the particles and their initial conditions (position, velocity, etc.) in the simulation.
- After completing the setup, you can run the simulation using the CST ES-PIC solver.
Please note that the specific steps and interfaces may vary depending on the version of CST Studio Suite you are using. The information provided here is a general guideline, and it's always recommended to refer to the official CST Studio Suite documentation or user guides for the version you have to get more detailed and accurate instructions. Additionally, keep in mind that the software may have been updated or changed since my last update, so be sure to check for any new features or changes in the software as well.
