主　　题：mesoscopic structure demultiplexer device bound states in continuum(BIC) EIT resonance 

摘      要：We investigate the electronic transport in a simple mesoscopic cross structure made of two wires(stubs)grafted at the same point along a quantum *** show that the structure may exhibit important phenomena such as bound in continuum(BIC)*** states are transformed into electromagnetically induced transparency(EIT)resonance by detuning slightly the lengths of the *** last phenomenon is used to propose and study a mesoscopic demultiplexer device with an input waveguide and two output *** give closed-form expressions of the geometrical parameters that allow a selective transfer of a given state in the first waveguide without perturbing the second *** effect of temperature on the transmission resonances is also examined by using Landauer-Büttiker *** analytical results of the dispersion relation and transmission and reflection coefficient are obtained using the Green s function method.
