Typical samples are up to a few centimeters thick and are not made of porous or lossy materials
Even metal surfaces are more interfering and act as lossy materials
In simulation and test board evaluations, Gore has found the loss performance of hybrid stripline transmission lines to be as good as or better than homogeneous striplines fabricated with mid-range lossy materials
with a dissipation factor of 0.
This option models the temperature rise in lossy materials
due to heating.
Not surprisingly, then, the shaped fiber lens also enables adequate gain/loss ratios in lossy materials
, and generally allows for the design of lasers with nearly arbitrary pump package requirements.
