An improved waveguide wall structure (30) and improved waveguide (60, 70, 80) using the new wall structure as the interior walls of the waveguide. The wall structure (30) comprises a sheet of dielectric material (32), a series of parallel conductive strips (34) on one side of the dielectric material (32) and a layer of conductive material (38) on the other side. Multiple conductive vias (39) are also included through the dielectric material (32) and between the conductive layer (38) and conductive strips (34). The new wall structure (30) presents as a series of parallel L-C circuits to a transverse E field at resonant frequency, resulting in a high impedance surface. The wall structure (30) can be used in waveguides (37, 60, 70, 80) that transmit a signal in one polarization or signals that are cross polarized. The new waveguide (60, 70, 80) maintains a near uniform density E field and H field component, resulting in near uniform signal power density across the waveguide cross section.

At least some aspects of the present disclosure feature a waveguide for propagating an electromagnetic wave. The waveguide includes a base material and a plurality of resonators disposed in a pattern, the plurality of resonators having a resonance frequency. Each of the plurality of resonators has a relative permittivity greater than a relative permittivity of the base material. At least two of the plurality of resonators are spaced according to a lattice constant that defines a distance between a center of a first one of the resonators and a center of a neighboring second one of the resonators.

A new and comparatively small type of open-ended microwave applicators has been disclosed. They are for example suitable for transmission into and reception from contacting objects such as protruding human bodyparts for inhomogeneity detection by tomographic methods. The applicators according to the invention are of the dielectric-filled open-ended ridged rectangular TE10 type, with an insert filling the ridge and having a higher permittivity than the surrounding space. The shape of the insert can be as a frustrum pyramid towards the opening. The overall design promotes narrow beamwidths and minimises nearfields and surface wave excitation.
