Antennas in Complex Environments

Antennas operating in complex environments, such as within plasmas or near dielectric materials present unique design challenges. High-power RF antennas can heat plasmas to millions of degrees, and dielectric materials can affect the near- and far-field patterns. Running simulations with VSimEM which is capable of full, self-consistent physics in the presence of plasmas and dielectrics allows engineers to determine the optimal antenna design for operation in complex environments.

VSimEM can compute the near- and far-field radiation patterns from antennas in complex environments, but it can also model the plasma behavior (collisions, secondary emission, etc.) in the presence of antenna-generated fields.

With VSimEM, plasma is modeled by particles or linear response functions and dielectrics are modeled to second-order accuracy.
