SUMMARY

    Leaky wave antennas (LWA) are very popular in the literature to generate a highly directional fan beam with a frequency controlled beam-scanning capability, The half-mode corrugated SIW (HM-CSIW) is used as a host waveguide for an array of half-elliptical ring slots to create a wideband LWA operating at 25 – 36.5 GHz. The paper is divided as follows: Section II describes the half-mode CSIW and the antenna design; Section III describes the simulated results, followed by Conclusions in Section IV.

LAY DEFINITIONS
  • substrate: A wafer (slice or substrate) is a thin slice of semiconductor material, such as a crystalline silicon, used in electronics for the fabrication of integrated circuits and in photovoltaics for conventional, wafer-based solar cells. The wafer serves as the substrate for microelectronic devices built in and over the wafer and undergoes many microfabrication process steps such as doping or ion implantation, etching, deposition of various materials, and photolithographic patterning
  • waveguide: A waveguide is a structure that guides waves, such as electromagnetic waves or sound, with minimal loss of energy by restricting the transmission of energy to one direction. Without the physical constraint of a waveguide, wave amplitudes decrease according to the inverse square law as they expand into three dimensional space
  • wave: In physics, a wave is an oscillation accompanied by a transfer of energy that travels through a medium. Frequency refers to the addition of time

Can europe recover its photovoltaic manufacturing capacity?

HIGHLIGHTS What: Figure 2 below illustrates the changing dynamics of the global PV market, and the influence of the Chinese PV market, 2 For the purpose of this report, IEA PVPS countries are those that are either member in their own right or through the adhesion of the EC. but also the fast pace of growth in India and emerging countries. Who: Melodie de l`Epine from the Japan Japan have published the Article: Snapshot of Global PV Markets -, in the Journal: (JOURNAL) of 23/04/2023 Future: Repowering is still relatively unusual given the age of the oldest installations but it is expected to increase in the near future – serial defects with backsheets manufactured in the period 2009 – 2011 is a good example as the past 2 years have seen a few hundred MW replaced. As penetration rates increase new governance models compatible with market and climate policy driven deployment targets will need to be established to ensure PV can be smoothly deployed.
