“…Given the respective advantages of nanowires and SIW [17][18][19], using nanowires to conceive Substrate Integrated Waveguide (SIW) devices is an interesting alternative. The basic idea underlying this concept is to use metallic nanowire arrays electrodeposited into a porous template to form the waveguide walls.…”

The chapter presents a review of properties and applications of a particular category of Substrate Integrated Waveguide (SIW) named NWSIW, for NanoWire-based Substrate Integrated Waveguide. The NWSIW topology combines metallic nanowires embedded in a porous template in order to form planar compact integrated waveguides; nanowires selectively grown in the template are used for building the walls of the waveguide, but also allow to achieve microwave functionalities such as filtering, isolation. Through the chapter the comparison made with classical waveguides including SIW will lead to a discussion on future perspectives and possible improvements of this NWSIW topology. Their performances will be explained and illustrated with regards to current state-of-the art, and based on results obtained at UCLouvain.

“…As outlined in Reference 11, high‐quality transmission lines are necessary to match the constraints of low cost and consumption, high density, high operational frequency, … Above 30 GHz, interferences and radiation losses degrade the performances of classical planar topologies such as microstrip and coplanar lines. Hence, the substrate integrated waveguide (SIW) concept 12 is an interesting solution.…”

A thorough study of the parameters influencing the operation of devices based on nanowired alumina substrate is presented. The basic structures are realized by growing metallic nanowires inside alumina porous substrate. The control of the areas wherein growth occurs allows building of various microwave devices supported on the filled template. The performances of these devices depend on the material parameters and topology/geometry in presence. These devices have the particularity to combine nanoscale, through the use of nanowires, and millimeter scale that is characteristic of microwave devices and their associated operating wavelength. The gap between the two‐scale ranges implies that analytical models and numerical simulation tools have to be combined to modelize and design performant microwave devices, such as Nanowired Substrate Integrated Waveguides (NSIWs) devices that are the subject of the paper. A deep parametric analysis of the properties and operation of the basic NSIW is presented and is followed by the illustration of two designs: a simple NSIW line, and an EBG NSIW filter.

This paper compares two laser-assisted processes developed by the authors for the fabrication of microwave devices based on nanowire arrays loaded inside porous alumina templates. Pros and cons of each process are discussed in terms of accuracy, reproducibility and ease of fabrication. A comparison with lithography technique is also provided. The efficiency of the laser-assisted process is demonstrated through the realization of substrate integrated waveguide (SIW) based devices. A Nanowired SIW line is firstly presented. It operates between 8.5 and 17 GHz, corresponding to the first and second cut-off frequency of the waveguide, respectively. Next, a Nanowired SIW isolator is demonstrated. It shows a nonreciprocal isolation of 12 dB (corresponding to 4.4 dB/cm), observed in absence of a DC magnetic field, and achieved through an adequate positioning of ferromagnetic nanowires inside the waveguide cavity.
