1. Gap Waveguide Technology- Electromagnetic Packaging and Transitions
Abstract : The scarcity of available frequency bands for new wireless communication systems, as well as the growing need for higher capacity, motivates the current interest in moving upwards in frequency. The millimeter wave frequencyrange is very attractive to allocate potential commercial opportunities such as short range wireless communications that allow high-speed data/video transmission, and automotive radars for both driver assistance and increasedsafety.

2. Gap waveguide for packaging microstrip filters & investigation of transitions from planar technologies to ridge gap waveguide
Abstract : Gap waveguide technology has proved to constitute an effective alternative for the design of microwave passive components, due to its advantages with respect to traditional planar technologies and standard waveguides. There is no requirement for conductive contact between the two different metal pieces making up a gap waveguide prototype, since one of these pieces makes use of a textured surface that eliminates any possible leakage of the field through the gap to the surface of the other metal piece above it.

4. Micromachined Gap Waveguide Devices
Abstract : Gap waveguide technology is a new technology that is well suited for millimeter and submillimeter applications. Compared to conventional rectangular waveguides, this technology does not need any solid conductive walls to confine the wave by utilizing metamaterial surfaces such as "bed of nails" that creates an artificial magnetic conductive surface (AMC).

5. Polymer-Based Micromachining for Scalable and Cost-Effective Fabrication of Gap Waveguide Devices Beyond 100 GHz
Abstract : The terahertz (THz) frequency bands have gained attention over the past few years due to the growing number of applications in fields like communication, healthcare, imaging, and spectroscopy. Above 100 GHz transmission line losses become dominating, and waveguides are typically used for transmission. READ MORE
