Experimental observation of the dual behavior ofPT-symmetric scattering

Experimental observation of the dual behavior of PT -symmetric scattering

We investigate experimentally parity-time (PT ) symmetric scattering using LRC circuits in an inductively coupled PT -symmetric pair connected to transmission line leads. In the single-lead case, the PT -symmetric circuit acts as a simple dual device—an amplifier or an absorber depending on the orientation of the lead. When a second lead is attached, the system exhibits unidirectional transpare...

the effect of classroom observation on eflteachers skills ans students outcomes

abstract the following study, in the first place, attempted to examine the effect of less experienced teachers participation in experienced teachers classes on their own skills and teaching methodology, in the second place, attempted to find out the role of teachers training in students achievements. for this purpose, 21 efl teachers were selected according to available sampling in kish l...

Experimental identification of unique angular dependent scattering behavior of nanoparticles

Background: Nanoparticles exhibit unique light scattering properties and are applied in many research fields. Methods: In this work, we perform angular resolved scattering measurements to study the scattering behaviour of random and periodic silver (Ag), and periodic polystyrene (PS) nanoparticles. Results: The random Ag nanoparticles, with a wide particle size distribution, are able to broadba...
