We have derived analytical expressions for the angular distribution P(α) of the power radiated by magnetic or electric dipoles located at distance z0 from a dielectric interface and oriented perpendicular to it. For dipoles in the rarer medium very close to the interface, evanescent waves in the dipoles’ near field give rise to strong radiation into the denser medium.

This paper presents a low-profile printed antenna with double U-shaped arms radiating circular polarization for the UHF RFID readers. The proposed antenna consists of double U-shaped strip structures and a capacitive feeding line to generate circular polarization. A part of the U-shaped arms is bent by 90° to direct the main beam parallel to the ground by: 2.

A theory on the propagation of plane waves through layers has application in ultra-high - frequency engineering independently of its use in the theory of propagation through the atmosphere. As an example, often a surface is coated with of some substance so as to absorb incident radiation, which can usually be regarded as being : Rudolf K.

The field line approaches asymptotically the straight line, and we see that it appears as if the line came from a point in the plane, indicated by vector, which is displaced with respect to the location of the ore, when viewed from the far field, it seems that the position of the Author: Xin Li, Henk F.

Electrodynamics is the physics of electromagnetic radiation, and electromagnetism is the physical phenomenon associated with the theory of electrodynamics. Electric and magnetic fields obey the properties ofa field due to any particular particle or time-varying electric or magnetic field contributes to the fields present in the same space due to other causes.

The radiation pattern in the horizontal plane of a dipole is a larger circle than that of the doublet. The vertical-radiation pattern lobes are no longer circular. They are flattened out and the radiation intensity is greater.

A monopole antenna is a type of dipole antenna formed by replacing one half of the dipole antenna with the ground plane at a right angle to the remaining half. If the ground plane is large enough, the monopole behaves exactly like a dipole because its reflection in the ground plane forms the missing half of.

• Electromagnetic radiation comprises both an Electric and a Magnetic Field. • The two fields are at right-angles to each other and the direction of propagation is at right-angles to both fields. • The Plane of the Electric Field defines the Polarisation of the wave. z x y Electric Field. Dipole emission near planar interfaces The problem of dipole radiation in or near planarly layered media is of signiﬁcance to many ﬁelds ofstudy.

It is encountered in antenna theory, single molecule spectroscopy, cavity quantum electrodynamics, integrated optics, circuit design (microstrips), and surface contamination control.
