An analysis for determining approximately the optimum position of the exciting source inside a spherical cavity for exciting any TE or TM mode is presented. For any TE or TM mode the orientation of ...

In the paper, impedance boundary problem of excitation of electromagnetic field inside a rotating spherical cavity with metal walls is formulated and solved rigorously. General solution of the problem ...

A composite accelerating cavity utilizing a resonant, periodic structure with a dielectric sphere located at a spherical conducting cavity center is presented. The resonator design is of the ...

Astronomers studying the vast reaches of the milky Way Galaxy have discovered a gigantic cavity in space, a sphere-shaped void located in the sky among the constellations Perseus and Taurus. The ...

Astronomers have discovered a giant, spherical cavity within the Milky Way galaxy; its location is depicted on the right. A zoomed-in view of the cavity (left) shows the Perseus and Taurus molecular ...

The location of the newly-discovered giant cavity within the Milky Way Galaxy is depicted on the right; a zoomed in view of the cavity (left) shows the Perseus and Taurus molecular clouds in blue and ...

Astronomers have discovered a humongous cavity in space while mapping interstellar dust. The sphere-shaped phenomenon may explain how supernovae lead to star formation.

This paper deals with a spherical cavity excavated in infinite homogeneous and isotropic strain-softening rock mass subjected to a hydrostatic initial stresses. By simplifying the strain-softening ...
