It remains unclear whether positive relative accommodation (PRA), negative relative accommodation (NRA), or binocular cross cylinder (BCC) values present differently when manifest refraction (MR) is performed before or after drug-induced mydriasis. T

In this paper, a novel method for generating a circularly polarized (CP) quasi-non-diffractive vortex wave carrying orbital angular momentum (OAM), based on the microwave holographic metasurface integrated with a monopole, is proposed. This method is

To fulfill the working condition at high pressure and temperature, a double-windowed pressurized volumetric receiver (DW-PVR) was proposed in this work. A computation model combining Monte-Carlo Ray Tracing method (MCRTM) and Finite Volume method (FV

A scheme of relay-assisted transmission system with few-mode all-optical relay is proposed in this paper to resist turbulence for atmospheric channels. The all-optical relay is composed of few-mode EDFA and photonic lantern which could amplify the di

In this paper we demonstrate a structure-simplified and cost-effective coherent receiver scheme for high splitting downstream transmission in next generation passive optical networks (NG-PONs). In such scheme, the simple 3dB coupler is used to replac

A dual-band circularly polarized (CP) antenna based on artificial mu-negative transmission lines (MNG-TLs) is proposed in this letter. By etching dumbbell-shaped slots on the microstrip and narrow gaps on the ground plane, the zeroth- and first-order

We propose a low-complexity and modulation-format-independent carrier phase estimation (CPE) scheme based on two-stage modified blind phase search (MBPS) with linear approximation to compensate the phase noise of arbitrary m-ary quadrature amplitude

A bio-inspired detector based on the artificial neural network (ANN) and genetic algorithm is proposed in the context of a coherent optical transmission system. The ANN is designed to mitigate 16-quadrature amplitude modulation system impairments, in
