Semicircular Patch-Embedded Vivaldi Antenna for Miniaturized UWB Radar Sensors
Sensors, 2020 A microstrip-to-slot line-fed miniaturized Vivaldi antenna using semicircular patch embedment is proposed in this study. The conventional Vivaldi antenna has ultrawide bandwidth, but suffers from low gain in the low-frequency band.

A Note on Rate of Convergence in Probability to Semicircular Law [PDF]
, 2011 In the present paper, we prove that under the assumption of the finite sixth moment for elements of a Wigner matrix, the convergence rate of its empirical spectral distribution to the Wigner semicircular law in probability is $O(n^{-1/2})$ when the ...

On the semicircular law of large dimensional random quaternion matrices [PDF]
, 2015 It is well known that Gaussian symplectic ensemble (GSE) is defined on the space of $n\times n$ quaternion self-dual Hermitian matrices with Gaussian random elements. There is a huge body of literature regarding this kind of matrices.

Phase‐shifted metasurface design for pseudo‐nondiffractive beam deflection
IET Microwaves, Antennas & Propagation, 2022 A transmission phase‐shifted metasurface (PSM) array has been proposed for non‐diffractive beam deflection. A PSM element consists of two identical semicircular rings and an I‐shaped structure, which is symmetrically printed on both sides of the F4B ...
