A shielded planar dielectric resonator with whispering gallery modes

The spectral and energy characteristics of two planar dielectric resonators (DRs), open and shielded from the curvilinear surface, excited in higher-order modes as whispering gallery modes (WGMs) in Ka-waveband are investigated. These resonators are formed by a thin (compared to the operating wavelength) disk dielectric structure, located between two conducting planes. Thus, the E-field of the resonator was limited along the height of the planar disk by two conducting surfaces. The resonance properties of such a structure are determined by the condition of total internal reflection of waves from the internal curvilinear surface of a dielectric disk. The carried out investigations shown that the unloaded Q-factor is increased at the arrangement of planar dielectric disk inside the ring metal shield at the certain ratio of the radiuses of the shield and dielectric disk. The Q-factor of the shielded resonant structure at the high-frequency edge increases to 40 %. The partial displacement of the resonant field of the WGMs modes from the dielectric to the air gap is the cause of this effect. It leads to decrease in losses in the dielectric material. A computer simulation of the WGMs fields in the planar DR was carried out using the CST Microwave Studio 2013 software to confirm this effect. In addition, computer simulation results shown that these WGMs in the planar DR are characterized by a homogeneous distribution of the resonant field along the axial coordinate. The perspectives of using planar DR in solid-state Ka-band oscillators are shown.

An Exploration of Subjective-Life of Spirituality and Its Impact

This paper contributes to the discussion on how morality may be uncertain when life orientation changes, for instance, from religious belief to spirituality. Accepting the ‘subjectivation’ thesis as a key concept in understanding the contemporary world, the spiritual realm is treated as a site on which the subjective turn has made a tremendous impact. That turn is investigated particularly in a comparison between “subjective-life” spirituality and “life-as” religion. Then, this paper asks what happens to morality when people’s religious belief disappears, changes, or evolves into spiritual experience. Educational practices are also viewed as a resonant field where the subjective turn has impacted on morality. The context of this paper refers to the subjective turn, as explained by The Spiritual Revolution: Why Religion is Giving Way to Spirituality. Then, the comparison of “life-as” and “subjective-life” is expressed according to their diverse values. Finally, the conclusion deals with the crucial points of morality in subjective life. In this regard, it is stressed that ‘subjectivation’ is a feature of our time, and presenting a remarkable challenge in the realm of values. Since their orientations are different, ‘subjective-lives’ have a different disposition in morality than the mode of “life-as”. Although it is impossible to generalize concerning whether or not spirituality is moral, nevertheless, it is expected that there will be challenges for religious education when dealing with spirituality.

Influence of hydrogenation on magnetoresonance characteristics of nanocomposite (CoFeB)mC100-m films

The influence of hydrogenation on the magnetoresonance characteristics of nanocomposite films during synthesis is studied by the method of ferromagnetic resonance (FMR). It is shown that introduction of hydrogen into the working chamber during the synthesis of film nanogranular structures (CoFeB)mC100-m leads to a change in a resonant field, to increase of the absorption line width, to reduction of anisotropy field in the film plane.
