The high-order Laguerre-Gaussian (LG) mode output from an end-pumped Nd:YVO<sub>4</sub> laser cavity with strong spherical aberration (SA) induced by short-focal-length lens is studied in this work. A long-focal-length L1 used the to expand and collimate beam, so that beam incident on another L2 undergoes a SA. Since ring-shaped LG modes different values of angular index <i>m&...

A giant cavity is a huge excavation which involves the greater part of a lobe or a whole lobe. When it occupies more than one lobe, we do not speak of giant cavity but of lung emptying, “Vaciamento pulmonar.” There are two types of giant cavities; and their differentiation is important since the treatment varies with the type. The first is the inflated, hypertensive giant cavity with a check-va...

An electromagnetic (EM) heating system is developed to achieve the rapid and uniform warming of cryopreserved biomaterials. Using the heating system, a rectangular resonant cavity is excited in TE101 mode at frequencies near 434 MHz. In experiments, a spherical phantom of biomaterial with a diameter of 36 mm is placed at the center of the cavity. The phantom is first cooled down to about -80 de...

The application of incremental plasticity conditions in the axisymmetric problem a spherical tank loaded with internal and external pressure is considered. Inhomogeneous stress distribution leads to increased limiting gradient stresses, which depend on cavity size. For tanks real dimensions, magnification limits are established for different laws approximation deformations’ constraint effect.

We extend our previous work on the electromagnetic Casimir-Lifshitz interaction between two bodies when one is contained within other. focus fluctuation-induced pressure acting cavity wall, which assumed to be spherical. This can positive or negative depending response functions describing and medium filling cavity. However, we find that, under general hypotheses, sign independent of geometry c...

Abstract Within the dual symmetric point of view, theory for seeking axion dark matter via haloscope experiments is derived by exactly solving electrodynamics equation. Notwithstanding that conventional presented in [9,11] more commonly used theory, we show has advantages to apply into theory. First, and perspective coincide under long-wavelength approximation. Moreover, can obtain an exact ana...
