Presents a study which compared magnetostatic surface wave propagation characteristics. Method of the study; Results and discussion; Conclusion.

Studies the effect of the addition of thorium on the propagation of magnetostatic forward volume waves at X band using a differential path delay line. Growth conditions of films of thorium substituted yttrium-iron garnet; Quantity that is useful in determining the quality of a thin ferrite film for propagation of magnetostatic waves; Conclusion.

III-V heterojunction bipolar transistors (HBTs) enjoy several advantages over their conventional silicon cousins. These include: (1) a thinner base and lower base resistance which yields higher gain and fmax; (2) high breakdown voltage; (3) low parasitics; (4) high power density. The combination of a thin base (higher fT), low base resistance (higher fmax), and low parasitics in particular make HBTs a suitable choice for high- frequency applications.
