Influence of Curvature Radius on Radiation Patterns in Multibeam Conformal Antennas

2006 European Microwave Conference, 2006
In this paper the effect of curvature radius on radiation patterns in multibeam antennas fed by a Butler matrix has been shown. Calculation results taking into account the change of amplitude and phase of the signal received at each radiating element caused by the array curvature for different radii have been presented.

Uniqueness of the Critical Point of the Conformal Radius: “Method of Déjà vu”

Lobachevskii Journal of Mathematics, 2018
Let $\mathbb D$ be the complex unit disc. By using the well-known ``Jack Lemma'', the authors give new conditions for the critical point of the conformal radius (hyperbolic derivative) to be unique. Some techniques used in the article use univalence criteria due to Sing, Shapiro, Szapiel and others.

Determination Coefficient of Stress Concentration Using a Conformed Display on a Circle of a Single Radius

Solid State Phenomena, 2021
Developed a mathematical model, which makes it possible to optimize, from the point of view of defect formation, the parameters of stress concentration in a deformable elastic body of the materials being processed, destruction is considered as a method for creating defects at a submicroscopic level in various media.

Estimates of Conformal Radius and Distortion Theorems for Univalent Functions

Journal of Mathematical Sciences, 2002
Let \(r(D,a)\) be the conformal radius of a simply connected domain \(D\supset\{0,1\}\) with respect to a point \(a\in D\). Considering the function \(r(D,\varepsilon)\) for \(\varepsilon\downarrow 0\) the author gives a simple proof of the recent result of \textit{E. G. Emel'yanov} [J. Math. Sci., New York 89, No.

Monte Carlo study of cycloamylose: Chain conformation, radius of gyration, and diffusion coefficient

Biopolymers, 2002
AbstractCyclic (1 → 4)‐α‐D‐glucan chains with or without excluded volume have been collected from a huge number (about 107) of linear amylosic chains generated by the Monte Carlo method with a conformational energy map for maltose, and their mean‐square radii of gyration 〈S2〉 and translational diffusion coefficients D (based on the Kirkwood formula ...

Minimization of the Conformal Radius under Circular Cutting of a Domain

Journal of Mathematical Sciences, 2001
The author considers the following problem. Let \(D\) be a simply-connected domain in the \(z\)-plane containing the origin with inner conformal radius \(R(D,0)=1\) for this point. Let \(\Delta_r= \{z\mid |z|0\). Let \(D_r\) be the component of \(D\cap\Delta_r\) containing \(z=0\).

Flexible, Conformal, Endfire Radiating, Electrically Small Antennas on a Conducting Cylinder With a Small Radius

IEEE Transactions on Antennas and Propagation, 2020
A design of a flexible, uniplanar, vertically polarized, Yagi-configured, electrically small antenna (ESA) that can be conformally mounted on a conducting cylinder with a small radius for endfire radiation is presented. To create a Yagi-configured antenna with both an electrically small size and uniplanar configuration, an interdigital structure is ...

An autonomous self-adapting conformal array for cylindrical surfaces with a changing radius

2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014
Conformal antennas are being used more often in modern wireless communication systems. Because of this increased usage, novel self-adapting arrays have been developed for improving the performance of wireless communication systems that use conformal antennas on changing surfaces.
