How to Produce 3D Far-Field Plots from 2D Axisymmetric RF Models
When modeling certain resonant structures, you can get the best of both worlds: 2D axisymmetry offers efficient computations while 3D far-field plots are available for postprocessing results.
Defeating Giant Movie Monsters Using Mathematical Modeling
The predator-prey equation can predict how we’d fare in a monster invasion, as well as real-world biology and ecology scenarios like shark overpopulation and tumor movement.
Happy Birthday, Joseph Keller
Mathematician Joseph Keller is best known for his geometrical theory of diffraction, but he also pursued other areas of study, even developing a teapot spout that doesn’t spill.
Samsung Amps Up Loudspeaker Designs with Simulation
Some organizations reach success and then shift the goal post. Take Samsung, for instance: Although they lead the market for televisions and smartphones, they set their eyes on another goal…
Engineering the Flow of Light Using Photonic Crystals
Did you know that the discovery of photonic crystals in 1980 came about because of an attempt to reduce the losses in semiconductor lasers in a specific frequency range?
Happy Birthday, Friedrich Bessel
Friedrich Bessel could have led a comfortable life had he stayed in his career at a commercial firm. Instead, he was inspired to study astronomy, physics, and planetary behavior and movement…
5 Facts for 50 Years: The Apollo 11 Lunar Landing
Think you know everything about the Apollo 11 mission? We go over 5 fun facts about the landmark aeronautical event in celebration of the 50-year anniversary.
Recursion and Recursively Defined Geometry Objects
Broadband antennas and metamaterials are 2 fields of engineering in which recursively defined geometry objects are a useful modeling capability. Writing methods makes this task easier.
