A nanospring is formed by first forming a stack of alternating layers of materials which have different susceptibilities to a selective etch solution. The radio communication device includes: a CCE allocation unit ; modulation units ; an arrangement unit ; and a radio transmission unit. The cold plate is further arranged to provide adapted flow of coolant to different portions of the processor whereby higher temperature regions receive a larger flow rate of coolant. Subcarriers selected from the respective groups in each of the subbands are assigned as an AMC subchannel to which an AMC scheme is applied. If desired, optical separation elements, such as dichroic filters, prisms, or gratings, can be positioned in front of each detector.
