Dynamical Casimir effect in a superconducting coplanar waveguide.
We investigate the dynamical Casimir effect in a coplanar waveguide (CPW) terminated by a superconducting quantum interference device (SQUID). Changing the magnetic flux through the SQUID parametrically modulates the boundary condition of the CPW, and thereby, its effective length. Effective boundary velocities comparable to the speed of light in the CPW result in broadband photon generation wh...
متن کاملDynamical Casimir effect in superconducting microwave circuits
We theoretically investigate the dynamical Casimir effect (DCE) in electrical circuits based on superconducting microfabricated waveguides with tunable boundary conditions. We propose implementing a rapid modulation of the boundary conditions by tuning the applied magnetic flux through superconducting quantum-interference devices that are embedded in the waveguide circuits. We consider two circ...
متن کاملMiniaturization of superconducting coplanar waveguide bandpass filters by cross coupling
For more size reduction of the high temperature superconducting coplanar waveguide (CPW) bandpass filter (BPF), we introduce the design method of the meanderline CPW quarter-wavelength resonator BPF. The exact admittanceand susceptance-inverters are calculated by using the 2.5-dimensional electromagnetic field simulator. The prototype YBCO miniaturized BPF (center frequency =10GHz, n=3, band wi...

متن کاملSurface loss simulations of superconducting coplanar waveguide resonators
Losses in superconducting planar resonators are presently assumed to predominantly arise from surface-oxide dissipation, due to experimental losses varying with choice of materials. We model and simulate the magnitude of the loss from interface surfaces in the resonator and investigate the dependence on power, resonator geometry, and dimensions. Surprisingly, the dominant surface loss is found ...
