Parallel Plate Capacitor Equation - Simulated

The Question A recent homework problem had us derive the parallel plate capacitor1 equation for electrostatics. This gives the capacitance of a parallel plate structure in terms of the plate area, distance between the plates and relative permittivity. The equation for this situation is: $ C = \epsilon_{R}\epsilon_{0}\frac{A}{d} $ After solving this problem for the analytical solution, I was curious to see how closely the result matched a 3D field solver.

Antenna Analysis from Ham Radio to PCBs

Has anyone else ever thought about why so many engineers are also active amateur radio operators? My theory is that there's just so much passion for the science and practical use of these complex electronic systems! We enjoy the problems, challenges and solutions so much that we want to find other ways outside of work to find those same experiences.
