We evaluate the new regional quasigeoid model (OTG12) for New Zealand using the method which utilises the discretised integralequation approach for computing the near-zone contribution. The far-zone contribution is computed by modi ed spherical harmonics of the geopotential. Adopting the remove-compute-restore computation scheme, the nearand far-zone contributions are computed for the residual ...

A spectral-domain volume-integral-equation method is developed for analyzing superconducting planar transmission lines. This method rigorously accounts for the complex conductivity, the finite metallization thickness, and the anisotropy of superconductors. Calculated effective dielectric constants and quality factors for microstrip lines and coplanar waveguides show good agreement with measured...
