Lithium be cut with a knife. When cut, it possesses a silvery-white color that quickly changes to gray as it oxidizes to lithium oxide. While it has one of the lowest melting points among all metals (180 °C), it has the highest melting and boiling points of the alkali metals. Lithium has a very low density (0.534 g/cm), comparable with pine wood. It is the least dense of all elements that are solids at room temperature; the next lightest solid element (potassium, at 0.862 g/cm) is more than 60% denser. Furthermore, apart from helium and hydrogen, it is less dense than
FEM Element It was originally called Electromagnetic Design System (EMDS). FEM Element FEM Element is a commercial finite element method solver for electromagnetic structures from EEsof. FEM Element can perform electromagnetic simulation of arbitrarily-shaped, passive three-dimensional structures. It is aimed at providing 3D EM simulation to designers working on RF circuits, MMICs, PC boards, modules, and signal integrity applications. It provides a full 3D electromagnetic field solver, a solid modeling GUI, and fully automated meshing and convergence capabilities for modeling arbitrary 3D shapes such as connectors, machined parts, components, bond wires, antennas, and packages. FEM Element is available with integration into Keysight
