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
A plane-parallel polarized radiative transfer model is described. The model is used to compute the radiance exiting a vertically inhomogeneous atmosphere containing randomlyoriented particles. Both solar and thermal sources of radiation are consider
Where there is light, there is polarized light. It is in fact difficult to find a source of light that is completely randomly polarized. As soon as light interacts with anything, whether through reflection, transmission, or scattering, there is oppo
This Letter proposes a method to balance the gain and loss of the orthogonally polarized emissions of dual wavelengths in a solid laser cavity. By adjusting the tilt angle of the uncoated glass plate inserted into the cavity, the gain and loss of the
We demonstrate a narrow-linewidth linearly polarized 1645 nm Er:YAG laser, directly diode-pumped by a fibercoupled continuous-wave laser diode at 1532 nm. Passive Q-switching is realized by a few-layer graphene saturable absorber. A maximum polarized
We numerically study the surface plasmon interference formed by tightly focused higher polarization order axially symmetric polarized beams (ASPBs) based on the vectorial diffraction theory. The definition of ASPBs is stated, and the optical setup 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
We report an all-fiber high power, single frequency large-mode area (LMA) linearly polarized ytterbiumdoped fiber amplifiers (YDFA) module, which is based on the master oscillator multi-stage power amplifiers (MOPA). The maximum output power is 43.8
We report on the high-power amplification of a 1064 nm linearly polarized laser in an all-fiber polarizationmaintained master oscillator power amplifier, which can operate at an output power level of 1.3 kW. The beam quality (M
In this Letter, we study the molecular alignment and orientation driven by two elliptically polarized laser pulses. It is shown that the field-free molecular alignment can be achieved in a three-dimensional (3D) case, while the field-free molecular o
We investigate the propagation of polarized light in fibrous tissues such as muscle and skin. The myofibrils and collagen fibers are approximated as long cylinders and the tissue phantom is composed of spherical and cylindrical structures. We apply M
A method for calculating the atmospheric parameters measurement accuracy requirement based on polarized reflectance retrieval is proposed. The at-sensor polarization states with different atmospheric parameters content are simulated based on the atmo
