The effect of the excitation frequency synthetic jet actuators on mean velocity issuing from an array circular orifices is investigated experimentally, focusing acoustic characteristics actuator’s cavity. Two cavity configurations are considered. In first configuration, jets generated by exciting a single, large having sixteen via piezoelectric elements. second volume configuration divided into...

We follow a generalized kinematic approach to compute the geometric phases acquired in both unitary and dissipative Jaynes-Cummings models, which provide fully quantum description for two-level system interacting with single mode of (cavity) electromagnetic field, perfect or cavity, respectively. In model, nonunitary effects arise from outflow photons through cavity walls incoherent pumping sys...

A tunable microwave scattering device is presented which allows the controlled variation of Fano line shape parameters in transmission through quantum billiards. We observe a non-monotonic evolution of resonance parameters that is explained in terms of interacting resonances. The dissipation of radiation in the cavity walls leads to decoherence and thus to a modification of the Fano profile. We...

Tumours in the oral cavity and oropharynx differ in presentation and prognosis and the detection of spread of tumour from one subsite to another is essential for the T-staging. This article reviews the anatomy and describes the pattern of spread of different cancers arising in the oral cavity and oropharynx; the imaging findings on computerized tomography and magnetic resonance imaging are also...

Our technique is based on moving a glass plate of known index and dispersion back and forth inside a ring resonator. In this way, any nonreciprocal phase shift induced by the motion of the glass manifests itself as a difference in the resonance frequencies of the cavity for oppositely propagating field directions. The precision measurement of small resonance frequency differences in a ring cavi...

Dissipative soliton resonance (DSR) is a phenomenon where the energy of a soliton in a dissipative system increases without limit at certain values of the system parameters. We have found that the DSR phenomenon is robust and does not disappear when perturbations are introduced into the model. In particular, parameter management is benign to DSR: the resonance property remains intact even when ...

We theoretically propose and numerically demonstrate that perfect feeding of a polaritonic system with full electromagnetic energy under one-port beam incidence, referred to as critical coupling, can be achieved in hybrid dielectric metasurface--${\mathrm{WS}}_{2}$ monolayer structure. Polaritonic where coupling strong are simultaneously attained, is determined by the relative damping rates cav...
