Standalone photovoltaic and battery microgrid design for rural areas
Energy Exploration & Exploitation, 2022 The remote location and many islands in Africa are experiencing a big power shortage and blackouts and they greatly necessitate electric power from standalone photovoltaic microgrid. In Rwanda, off-grid solar systems are at their infancy level and their

Deep reflector prime focus feed for space communication
The Journal of Engineering, 2021 In this paper, design of a prime‐focus feed for a deep reflector, Earth–Moon–Earth space communication system is described. The feed is based on a circular waveguide equipped with two chokes in order to minimise sidelobes and illuminate the deep dish ...

Transmitters for Combined Radio Over a Fiber and Outdoor Millimeter-Wave System at 25 GHz
IEEE Photonics Journal, 2020 In the modern wireless networks, millimeter-wave radio-frequency (RF) bands are becoming more attractive as they provide larger bandwidth and higher data rates than the today-used systems operating at frequencies below 6 GHz.

Controlling Electromagnetic Fields
Science, 2006 Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D , magnetic induction field B , and Poynting vector B —are all ...

ELECTROMAGNETIC FIELDS ON FRACTALS [PDF]
Modern Physics Letters A, 2006 Fractals are measurable metric sets with non-integer Hausdorff dimensions. If electric and magnetic fields are defined on fractal and do not exist outside of fractal in Euclidean space, then we can use the fractional generalization of the integral Maxwell equations. The fractional integrals are considered as approximations of integrals on fractals. We
