Compared to typical performance, our TECs deliver up to 60% higher heat pumping density and 30% lower energy consumption in a very thin form factor to support pluggable transceivers. Webpersion diagram—both ω and ~k are conserved quantities, meaning that a band diagram maps out all possible interactions in the system. (Note also that ~k is not required to be real; complex ~k gives evanescent modes that can exponen-tially decay from the boundaries of a finite crystal, but which cannot exist in the bulk.) the spider miraculous
