Abstract:

In this study, the principle of band suppressing an UWB antenna by attaching a small resonator is explained by developing its equivalent circuit. The realized UWB antenna is a conical monopole antenna that contains a split loop for band suppression. The conical monopole antenna corresponds to a transmission line terminated with load impedance, and the split loop is an LC resonator. The coupling between the conical monopole antenna and the split loop is represented as mutual inductance. Equivalent circuits for the UWB antenna suppressing single band [WLAN] and dual band [WLAN, WiMAX] have been

Abstract:

The motion of test particles and light rays in the perturbed gravitational field around a global monopole is studied. The metric of the monopole was previously obtained by solving the linearized semiclassical Einstein equations (Hiscock). The bending of light ray passing by such a monopole has contributions from the conical object as well as from the perturbed terms. The possibility of trapping particles in the perturbed gravitational field is also discussed.

Abstract:

A stepped cylindrical antenna with a higher-order mode ring patch for wideband conical radiation pattern is proposed. To accomplish a low profile with wideband conical radiation characteristics, a stepped cylindrical monopole and a TM41higher-order mode ring patch with four shorting pins are utilized. The proposed antenna has a monopole-like radiation pattern with a wide 10-dB return loss bandwidth of 11 GHz (2 GHz–13 GHz). It can cover various wireless services, such as wireless broadband (WiBro; 2.3 GHz–2.39 GHz), wireless local area networks (WLAN; 2.4 GHz–2.484 GHz, 5.15 GHz–5.35 GHz, and

We show how one may obtain conical (Dirac) dispersions in photonic crystals, and in some cases, such conical dispersions can be used to create a metamaterial with an effective zero refractive index. We show specifically that in two-dimensional photonic crystals with C4v symmetry, we can adjust the system parameters to obtain accidental triple degeneracy at Γ point, whose band dispersion comprises two linear bands that generate conical dispersion surfaces and an additional flat band crossing the Dirac-like point.

Abstract:

A single source firing below the surface of the ocean, because of the surface reflection, has directionality. Directionality is defined as variation of amplitude with angle. Conceptually the radiation field of such a source may be treated as due to a vertical dipole of finite length. A formulation for transforming data recorded with a dipole wavelet to that of a monopole or plane‐wave wavelet is derived in this study. We have found that the cylindrical τ-p transform allows the removal of the source waveform and amplitude variation in the data due to the dipole and observed on the offset‐time r

Abstract:

In the scope of broadband radiators, the biconical antenna, or its monopole conical counterpart, is long known to be a proper choice. One common form of such radiator, the spherically capped conical antenna (SCCA), has closed-form solution to its input impedance, from which the broadband performance potential is easily verified. Nonetheless, from the design perspective, apart from a few clues inferred from existing solutions, little is found to accurately guide the choice of the main geometrical parameters of the antenna that will enable it to comply with a set of imposed bandwidth requirement

A carbon fiber reinforced polymer (CFRP) laminate, with the top layer consisting of shredded fibers, is proposed and manufactured. The shredded fibers are aligned randomly on the surface to achieve a more isotropic conductivity, as is desired in antenna applications. Moreover, fiber shreds can be recycled from carbon fiber composites. Conductivity, permittivity, and permeability are obtained with the Nicolson-Ross-Weir method from material samples measured inside rectangular waveguides in the frequency range of 4 to 6 GHz. The decrease in material anisotropy results in negligible influence on

Thus, we refer to them as conical backgrounds. In terms of the angular deficit value, we derive the perturbative expression for the scalar Green’s function and compute i

In borehole seismic experiments the presence of the borehole has a significant effect on observations.

To overcome this problem, we use the concept of an effective source/receiver array to replace the explicit representation of the borehole by a distributed seismic source/receiver.

Abstract:

Abstract The offshore wind power industry is the branch of electric energy production from renewable sources which is most intensively developed in EU countries. At present, there is a tendency to install larger-power wind turbines at larger distances from the seashore, on relatively deep waters. Consequently, technological solutions for new supporting structures intended for deeper water regions are undergoing rapid development now. Various design types are proposed and analysed, starting from gravitational supports (GBS), through monopiles and 3D frame structures (jackets, tripods), and endi

Abstract:

Cosmos (Cosmos bipinnatus Cav., Asteraceae) is an herbaceous plant that is grown for landscape use. During August and September of 2008 in five public and three private gardens located in Monopoli (Apulia, southern Italy), 3 to 8% of the plants showed severe symptoms of vine decline, stunting, gradual yellowing and wilting of the leaves, and final collapse of the whole plant. External symptoms were associated with brown or black streaking of the vascular tissue of roots, collar, and stem. Dead plants had numerous microsclerotia embedded in the xylem of plant tissues. Stem, collar, and root sec

Abstract:

Context. The disk-outflow connection is thought to play a key role in extracting excess angular momentum from a forming protostar. HH30 is a rare and beautiful example of a pre-main sequence star exhibiting a flared edge-on disk, an optical jet, and a CO molecular outflow, making this object a case study for the disk-jet-outflow paradigm. Aims. We aim to clarify the origin of the small-scale molecular outflow of HH30 and its link and impact on the accretion disk. Methods. We present ALMA 0.25″ angular resolution observations of the circumstellar disk and outflow around the T Tauri star HH30 in

Abstract:

AbstractIn this letter, a compact pattern‐reconfigurable (PR) antenna for indoor communication is proposed, which can provide one conical, one broadside, and two tilted patterns. The proposed antenna comprises a shared radiation patch with two highly isolated ports and a reconfigurable feeding network. By activating each port independently, a dipole mode with broadside pattern and a monopole mode with conical pattern are acquired, respectively. Meanwhile, inspired by the theory of common and differential modes, two tilted patterns toward and are realized by combining dipole and monopole modes.
