An Enabling Multi-Operation Branch-Line Coupler

In this paper, an enabling multi-operation branch-line coupler is proposed initially.The proposed design is configured by ±90° and 180° transmission Performance lines, and the main advantage is that the proposed design can be applied in three different system connection schemes as shown in Fig.1.Corresponding to the three schem

Turbulence in a Coronal Loop Excited by Photospheric Motions

Photospheric motions are believed to be the source of coronal heating and of velocity fluctuations detected in the solar corona.A numerical model, based on the shell technique applied on reduced magnetohydrodynamics equations, is used to represent energy injection due to footpoint motions, storage and dissipation of energy in a coronal loop.Motions
