In this paper, we present a two-dimensional dynamic metasurface aperture to perform computational polarimetric microwave imaging for the first time.First, a novel tunable dual-polarized metamaterial radiator element integrated with two PIN diodes is designed to Air Filter radiate and capture crossand co-polarized field components.The diodes placed
Planar Cell Polarity (PCP) is an evolutionarily conserved Bar Height Stool characteristic of animal tissues marked by coordinated polarization of cells or structures in the plane of a tissue.In insect wing epithelium, for instance, PCP is characterized by en masse orientation of hairs orthogonal to its apical-basal axis and pointing along the proxi
In the present system of capitalism, the money and interest rate have a special place in macroeconomics and play a major role in conducting monetary policies and determining economic activities level.Classical school believe that interest rate is a real phenomenon.However, Keynes argued that interest rate is a money phenomenon.Silvio Gesell reasone
With the development of the Internet of Things (IoT for short), innumerable Wireless Sensor Networks (WSNs) are deployed to capture the information of environmental status in the surrounding physical environment.The data from WSNs, called sensor data, are generated in high frequency.Similar to data of other open-loop applications, for example, netw
In this manuscript, an implementation of a tunable nonlinear phase compensation method is demonstrated on a typical femtosecond hybrid laser consisting of a fiber pre-amplifier and an additional solid-state amplifier.This enables one to achieve constant laser pulse parameters over a wide range of pulse repetition rates in such a laser.As the gain i
