A solution of Equations (3) for material objects with complex surface shape and for the coupling hole [SIGMA] of arbitrary geometry encounters serious mathematical difficulties.
A coupling hole is designed on one planar mirror, and a source is placed out of the cavity to excite the cavity through the coupling hole.
Figure 4 shows the relationship of [Delta]l and relative permittivity [[Epsilon].sub.r][prime] (referenced to the coupling hole's short circuit, [Epsilon][double prime] equals approximately 0) at 4.5 GHz.
Let us formulate a general problem of electromagnetic waves excitation, scattering, and radiation by a material body of finite dimensions in presence of a coupling hole between two arbitrary electrodynamic volumes.
To compare this with no coupling hole, the electric field pattern without a hole is shown in Figure 5.
Tenders are invited for Situ repair of ovality of coupling Holes of Turbine shaft at Runner end of Generating Unit # 3 of Nimoo Bazgo Power Station.
Due to coupling symmetry and loading symmetry, load was applied on two adjacent coupling holes. The results obtained will also be symmetric in nature.
