TLM cylindrical model of a coaxially loaded cylindrical cavity

This paper explores the effectiveness of the TLM method based on the cylindrical grid for the purpose of an analysis of a cavity with a circular cross-section and coaxial load. To consider the advantages of the cylindrical over rectangular TLM grid, coaxial inner load with different dielectric properties and dimensions have been used. Obtained numerical results have been verified comparing with corresponding analytic and measured results.
