On the Field Patterns in Elliptic-Shaped Microshield Lines Loaded with Left-Handed Materials by the Edge-Based Finite Element Method

The field patterns in elliptic-shaped microshield lines loaded with left-handed materials are analyzed by edge-based finite element method. The left-handed material is defined by assigning to it a negative permittivity and negative permeability simultaneously. The field patterns include the dominant mode and the first higher-order mode. Some illustrated figures provided in this paper are considered useful in novel microwave and millimeter devices.
