assumed to be about 200,000. Assuming that the rectenna is supported by buildings with about 100 m height, many all-weather athletic fields may be placed in the city. Moreover, we may construct an international airport with six runways around the rectenna. A high speed traffic network (linear motor car) will link the airport and other cities together. The electric power produced by the SPS will supply the necessary electric energy for this traffic system. Hogline Rectenna with CMSA Let us discuss the hogline rectenna using the CMSA. If we place the CMSA horizontally, sunlight is screened by the rectenna. Instead, we propose the hogline rectenna with the CMSA as shown in Fig. 2. The hogline concept is discussed in the literature [3]. The reflector is composed of wires. Although microwaves from the SPS are reflected by the wires, sunlight passes through the reflector. Fig. 2 shows the case where longitudinal polarization is employed. If transverse polarization is employed, we set the wires perpendicularly. If necessary, the CMSAs are arrayed as shown in Fig. 3. On the plane containing the focal line, we have the radiation pattern shown in Fig. 4 which is the same as that of the CMSA. On the plane perpendicular to the focal line, we have the radiation pattern which is determined by the reflector of the dimension Da shown in Fig. 2 and grazing angle of the SPS. Namely, the radiation pattern is determined by the effective dimension D shown in Fig. 5 which will be discussed in
