As discussed in the last tutorial, there are three important parameters to determining the impedance of a coax line, whether it’s flexible RG-59, helix or rigid coax: the ratio of the inner and outer ...

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

For most design engineers, study of waveguide technology ended when they got their last degree. The only time waveguide comes up is to use it as a last resort in applications such as millimeter-wave ...
