摘要：Optimum Heat sink design is extremely essential for proper operation of IMPATT diodeoscillators. For steady and safe operation of the oscillator without burn-out of the device,properly designed heat sink must be provided. In this paper authors have presented a newmethod for getting optimum designs of heat sinks capable of serving the above purpose.Moreover analytical solution of the Laplace equation for steady state heat transfer problemswith proper boundary conditions for arbitrary geometries is sometime very difficult to find out.That is why numerical techniques like Finite Difference Method [FDM] can be used as veryuseful tool by which the solutions can be found out easily without much computational error. Inthis work authors have applied Finite-Difference Method to find out 2-D TemperatureDistribution inside the ordinary mesa diode as well as ring diode mounted on semi-infinitediamond and copper heat sinks. Results are presented in the form of plots and tables useful fordesign.
