High-powered satellites use electromagnetic waveguides to deliver energy from one component to another. Typically, they are made of heavy, inflexible metal tubes with an even heavier flange on either ...

In an EM wave absorbent chamber, an LED is illuminated at 10 cm by microwave energy delivered through a twist bellows waveguide. Scale bar is 100 mm. The inserts upper left show the twist bellows ...

Routines to create rounded corners, with either circular rounding, or continuous curvature rounding with no sudden curvature transitions. Provides rounding of corners or rounding that preserves corner ...

Box pleating is arguably the standard framework of modern super-complex origami designs, as the creases are much more predictable and manageable than those found in the traditional 22.5 degree system ...

A simple rectangular model with some analytical solutions for its preliminary gravity analysis is definitely meaningful and practicable here. It is well known that we cannot derive simple analytical ...

Abstract: A new method powered by an artificial neural network (ANN) is studied for resonant-mode recognitions of a rectangular dielectric resonator antenna (DRA). Different rectangular DRAs were ...
