Modeling the Speed and Stealth of the Darkstar
What would the shock waves around the Darkstar really look like at Mach 7.5? How stealthy is this hypersonic jet? Here, we use modeling and simulation to find out.
Learning from the Two-Capacitor Paradox: Do Capacitance and Inductance Exist?
What is the two-capacitor paradox? How can it be resolved with modeling and simulation? Do capacitance and inductance exist? Get answers here.
Understanding Higher-Order Diffraction
Explore how to use the Ewald sphere to study diffraction from planar periodic structures. (Interact directly with the model to get the full picture!)
From TV Signals to Toasting: Tuning a Yagi–Uda Antenna to Heat Muffins
See how modeling and simulation can be used to test an unconventional heating method. Here, we explore how a Yagi–Uda antenna performs as a hypothetical oven replacement to heat muffins.
Modeling Dispersion in an Electric Currents Model
As of COMSOL Multiphysics® version 6.2, new electrical dispersion modeling capabilities are available. This functionality is especially important for modeling insulators and living tissues.
Building a Metalens Design App with COMSOL Multiphysics®
Here, we explore how to build a simulation app for reflective metalens design, which can easily be compiled into a standalone app.
Modeling Periodic Electric Signals and Their Thermal Effects
Electrical pulse trains can be applied to human tissue for electroporation and thermal ablation. Learn how to model such signals via a Fourier transform approach.
Understanding the Transient Electromagnetic Excitation Options
Looking to model electrical signals that vary arbitrarily in time? We suggest using the Electric Currents interface. Learn why here.
