conical helix state is realized with a modulation vector Q ≈ 105 μm in Cu 2OSeO 3 corresponding to a wavelength λ = 2π Q ≈ 60 nm. Due to this periodicity, the dispersion of conical spin waves is back-folded giving rise to a spin wave Brillouin zone of size Q (see Fig. 1D). As a result, two conical spin waves (helimagnons) with

An efficient magnetically coupled wireless power transfer system using a conical coil structure is presented. The use of conical inductors instead of traditional planar coils increases the self-resonance frequency of the transmitter resonator while maintaining the flux linkage to the receiver side. Electromagnetic (EM) and circuit simulation results …
It is shown that shaped-conical radiation patterns can be realized by extending the resonant fractional-turn quadrifilar helix to an integral number of turns, i.e., the radiated energy can be concentrated into a cone with the gain decreasing from a maximum at the edge of the cone to a local minimum at the center. This pattern shape is near optimum …
1. Introduction. With the rapid development of GPS and SNS, antenna plays a more crucial role on the system performance. Moreover, cardioid-shaped radiation patterns with good circular polarization in a broad bandwidth are required tremendously for satellite communication and navigation systems [].Quadrifilar helix antenna (QHA), …
Type of dielectric material used as the substrate, specified as a dielectric object. You can specify only one dielectric layer in the helix object. When using the Substrate property, specify the same radius for all the turns. When using a dielectric material other than air, the number of turns in the helix should be greater than 1.

The conical helix can be defined as a helix traced on a cone of revolution (i.e. a curve forming a constant angle with respect to the axis of the cone), or a rhumb line of this cone (i.e. a curve forming a constant angle with the meridians); it is not a geodesic of the cone. In concrete terms, we get a conical helix when we trace a path with constant slope on a …

The radiation characteristics of a monofilar conical-helix antenna are investigated on the basis of the theoretical current distribution. It is shown that the current distribution may be divided into two regions, and that a decaying current from the feed point to a point of the first minimum is the major contributor to the radiation. It is also found that the wideband …
