Abstract: Various embodiments for a coaxial low-pass filter are described herein. Generally, the coaxial low-pass filter is operable to generate a stopband by a controlled generation of transmission zeroes within a stopband frequency range. The coaxial filter includes a plurality of cavity junctions, each of the plurality of cavity junctions operable to generate at least one corresponding cavity-specific transmission zero through a dual-mode coupling of a transverse electromagnetic and a transverse magnetic resonant mode, the at least one cavity-specific transmission zero being generated at at least one corresponding frequency located within the stopband frequency range, wherein for each cavity junction, the location of the cavity-specific frequency is adjusted by adjusting at least one property of the cavity junction, wherein a scattering of the locations of each of the cavity-specific transmission zeroes, generated by each of the plurality of cavity junctions, generates the stopband at the desired frequency range.
