PDT), with the signal received by NASA's Deep Space Network antenna complex in Canberra, Australia.
For instance, invisible rods could be used as supports for a miniature antenna complex connecting two optical chips.
However, fabrication with 12 switches makes such reconfigurable antenna complex in structure and expensive in cost.
PSII is a complicated complex comprising outer light-harvesting complex (LHCII), core antenna complex (including CP43 and CP47), reactive center complex (RC) and Manganese cluster, and its components are so located and assigned as to ensure the quick and efficient energy and electron transfers.
It is generally believed that the core antenna complex CP43 and CP47 receive energy from outer LHCII system and assistant antennas, and then transfer the energy to RC complex to complete the energy transfer.
the significance of the pigments in the reaction center as well as those in the antenna complex
several students, depending on the size of the class, designated as chlorophylls a and b, and carotenes and xanthophylls in the antenna complex
We meet the two chlorophyll a molecules in the reaction center, surrounded by the antenna complex pigments, and other characters in the play.
They will then examine the pigments' photophysics, appreciating (1) the efficient absorption of visible sunlight accomplished by plant pigments and (2) the energy- and electron-transfer processes between the antenna complex and the reaction center and between the reaction center and the primary electron acceptor.
The Australian antenna complex is located near Canberra while the Spanish complex is near Madrid.
Not to be ignored are the costs (in today's ESM systems) of the interface processor and the RF and video cabling between the upmast antenna complex and the below-deck receivers.
