A dual-band omnidirectional circularly polarized antenna is proposed. The antenna comprises back-to-back microstrip patches fed by a coplanar waveguide. A very low frequency ratio of 1.182 has been achieved, which can be easily tuned by adjusting fo
In accordance with nonperturbative quantum scattering theory, we investigate photoelectron angular distributions (PADs) from above-threshold detachment (ATD) of negative ions irradiated by circularly polarized few-cycle laser fields. Electrons ejecte
In this Letter, we focus on the theoretical analysis of the relativistic energy and angular distributions of the ejected photoelectrons during the relativistic tunnel ionization of atoms by intense, circularly polarized light. We make a small modific
Nonsequential double ionization (NSDI) of noble gas atoms in counter-rotating two-color circularly polarized (CRTC) laser fields is investigated. A scaling law is concluded by qualitatively and quantitatively comparing the momentum distributions of t
A Compact, Omni-directional, Circularly Polarized Microstrip Antenna - Presentation of an omni-directional, circularly polarized antenna using a zero-order resonator with arc-shaped stubs
Polarization switching (PS) characteristics in a 1550 nm vertical-cavity surface-emitting laser (VCSEL) subject to circularly polarized optical injection (CPOI) are experimentally investigated. The results show that, under different biased current, a
We experimentally demonstrate N^+_2 lasing actions at the wavelengths of 353.3, 353.8, and 354.9 nm using a circularly polarized femtosecond laser. The three laser lines correspond to the B2Σ+u(v'=5, 4, 3)->X2Σ+g(v'=4,3,2) transitions, respectivel
We present the study of the interaction of an intense circularly polarized pulse with a solid target with one-dimensional (1D) particle-in-cell (PIC) simulation. The evolvement of ion motion with time is explained by a purely kinetic descr iption and
