Example waveguide devices for guiding radio frequency signals are described. One example waveguide device includes an elongate flexible tubing having an elongate shape. The elongate flexible tubing includes an inner surface defining an elongate airtight cavity. The elongate airtight cavity extends from a first end of the elongate flexible tubing to a second end of the elongate flexible tubing. The first end is configured to couple the radio frequency signal into and/or out of the elongate airtight cavity. the inner surface of the elongate flexible tubing is configured to guide the radio frequency signal along the waveguide device. The second end is configured to couple the radio frequency signal out of and/or into the elongate airtight cavity. When the elongate airtight cavity is filled with a pressurized gaseous fluid, the elongate flexible tubing is configured to retain its elongate shape.

The invention concerns a flexible waveguide device (10), of the bellows type, for guiding a radio frequency signal at a given frequency range. The device comprises: a core (12) comprising outer and inner side walls (14a, 14b), the inner walls (14b) delimiting a waveguide channel (16); two fixing flanges (18a, 18b) connected to or integral with respective ends of the core (12), and at least one flexible corrugated portion (20) formed on a part of the outer side walls (14a) of the core (12) and comprising a plurality of circumferential ribs (22) adjacent to each other. Each rib (22) is devoid of corrugation along its circumference. The invention also relates to a method of manufacturing the flexible waveguide device.

A flexible and twistable terahertz waveguide assembly has a flexible waveguide with waveguide flange connectors at its ends. The flexible waveguide comprises a segmented tube of a plurality of tube segments which are connected to each other. The tube encloses a dielectric waveguide which is held by means of threads (filaments) at the center of the tube. The individual segments are tiltable and/or pivotable against each other, allowing bending and twisting of the waveguide cable.

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.
