Last month, this column discussed some of the fundamental concepts of selecting coaxial transmission lines. That included low-power flexible lines as well as some issues involving high-power rigid ...
Measurement of complex permittivity by rectangular waveguide method with simple specimen preparation
Abstract: The characterization of materials by rectangular waveguide method usually requires a sample holder and a complicated procedure of preparing specimen in order to limit the air gaps between ...
Abstract: In this work a new one-port tapered rectangular waveguide (RW) sensor is employed for determining the dielectric constant of different vegetable oil samples. The proposed design uses the ...
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 ...
