A half-wave dipole antenna is used as a standard of comparison. Two important properties of the finite-length, center-fed dipole antenna are the radiation pattern and the input impedance. The radiated electric field is found through Maxwell’s equations, and in...
Reactive near-field region and Radiating near-field region both termed as nearfield. Radiating far-field region simply called as far-field. The field, which is very near to the antenna isreactive near fieldornon-radiative fieldwhere the radiation is not pre-dominant. The region next to it ca...
The design process and performance of the metasurface are examined, taking into account the design of the unitcell and the analysis of the phase-synthesized array. The fundamental concept, as per transmitarray theory, involves adjusting the phase of the electric field radiation or the current sources...
NEAR-FIELD Near-field vs Far-field Any antenna can be successfully measured on either a near-field or far-field range, with appropriate implementation. There are significant cost, size, and complexity details which will lead to a recommendation of one type over the other. In general, far-...
Experiments indicate the presence of three regions: a region close to the burner surface where plume entrainment rates are independent of the fuel flow (or heat release) rates; a far field region above the flame top, where a simple point source model correlates the data reasonably well; and ...

regions23. Although it is highly unlikely that air pollution can be eliminated completely, it is realistic to imagine that air pollution can be reduced substantially through effective public policy, and indeed it already has been in various parts of the world. It is therefore an important ...
Focusing on near-field effects for smaller impacts, however, requires us to consider the complications of oblique impacts. An asteroid on an oblique trajectory passes through, and preheats, much more of the atmosphere, spreading effects over a wider area, while at the same time suffering ...
innovative beam designs enabled by near-field technologies, focusing on non-diffractive beams (such as Bessel and Airy) and orbital angular momentum (OAM) beams, addressing both hardware architectures and signal processing frameworks, showcasing their revolutionary potential in near-field communication ...
