Design segmented slot waveguide for integrated waveguide modulator
2016 IEEE International Conference on Semiconductor Electronics (ICSE), 2016In this article, segmented slot waveguide structures are designed and analysed numerically. We present a theoretical investigation of overlap factors and low half voltage for different segmented slot waveguide structures to determine optimised geometrical dimensions based on slot widths.

Millimeter-wave sinusoidal slotted waveguide antenna
2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES, 2010A travelling-wave sinusoidal slotted waveguide antenna is investigated. To the best of our knowledge, a sinusoidal slot is applied to the narrow face of a rectangular waveguide at this frequency range, for the first time. In experiment, far-field and S-parameters are measured.

Non-birefringent cross-slot waveguide
CLEO/Europe - EQEC 2009 - European Conference on Lasers and Electro-Optics and the European Quantum Electronics Conference, 2009Silicon photonics is a rapidly advancing technology [1]. Silicon based slot-waveguides for high optical mode confinement of quasi-TE (vertical slot) and quasi-TM (horizontal slot) mode have been demonstrated independently [2,3]. These structures are highly birefringent, which limits their usability in photonic devices.

Radome integrated slotted waveguide antennas
2017 XI International Conference on Antenna Theory and Techniques (ICATT), 2017The development of slotted waveguide antennas with an integrated radome is discussed. The integrated radome is intended to improve the resistance of slotted-waveguide antennas against complex environmental conditions and to extend application areas of the antennas.

Annular slots for circularly polarized slotted substrate integrated waveguide array
The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014A new type of circularly polarized slot radiator is presented. Good polarization performances are reached for both left-hand and right hand circular polarization (LHCP, RHCP). The slot configuration consists of an annular slot placed correctly on the upper wall of the waveguide. Several annular contours and positions have been tested and compared.

A WAVEGUIDE SLOT SWITCHING TECHNIQUE
1963Abstract : A series of experiments is described on a novel technique which permits a slot radiator in a waveguide to switch its radiation on and off by means of a compact circuit located at the plane of the slow and within the wall thickness of the waveguide feed line.
