A new platform for engineering chiral electron pathways offers potential fresh insights into a quantum phenomenon discovered ...

A research team at POSTECH (Pohang University of Science and Technology) has successfully developed the world's first technology that enables uniform and even stretching across multiple pixels in a ...

Southern Oscillation’s global reach and complex ocean–atmosphere interactions across timescales, two simple, elegant equations capture its key dynamics and defining properties.

The dipole’s theoretical gain is around 2 dBi (dB relative to isotropic). Its radiation pattern is simple and often characterized ... (often simply called “Yagi”) is constructed from an array of ...

As we show, this selectivity drives two posts coated with distinct enzymes to form a dipole-like structure ... consumption of the solute (reactants and products). Patterns generated by 9×9 square ...

Abstract: A new method for pattern reconfigurable antenna (PRA) design is introduced on the basis of a two-element dipole array model in this communication. Firstly, a two-element dipole array loaded ...

Optical holograms use two light beams to create a 3D image: one beam hits the object and bounces off of it, while the other shines on a recording medium. The hologram forms from the pattern of ...

However, in realistic array antennas with a finite number of antenna elements, the edge element patterns ... magneto-electric dipole (MED) antenna elements. The following is a summary of the key ...

Increasing the number of channels in dipole antenna arrays requires modification to the single dipole antenna element geometry because the length of dipole antennas in free space (∼50 cm at 297.2 MHz) ...

In this paper, we describe 2 kinds of printed dipole arrays and compare the performances of these arrays in term of reflexion coefficient, radiation pattern and dimensions. It is interesting to design ...
