Abstract: The coupled transcendental equations describing cutoff frequencies of TE and TM modes are deduced for a rectangular waveguide with arbitrary wall impedance. In the case of TE modes, their ...
One of the shape primitives you'll use most often in your OpenSCAD designs is the cube. Rounding the edges of cube-like objects impacts both the visual appeal and functional aspects of the final ...
Some standard modules for making 3d shapes with attachment support, and function forms that produce a VNF. Also included are shortcuts cylinders in each orientation and extended versions of the ...
