YAGI(5) File Formats Manual YAGI(5)NAME
yagi - yagi binary output format
DESCRIPTION
This manual page describes the output format of the file created by the Yagi-Uda project's yagi program. The file is a binary file with a
header of 100 bytes. The header consists of:
offset(bytes) information data-type
0 elements int
4 driven int
8 parasitic int
12 min_frequency double
20 max_frequency double
28 design frequency double
36 step_frequency double
44 angular_step double
52 0 double
92 0 double
Following the header, there starts the coordinates(x,y,l) of each
element and the voltage applied to each element. Then we write
the element currents one after the other, at each frequency.
Hence the element currents will be written 12,000 times with a
3 element yagi analysed at 4,000 different frequencies. All complex
data is stored in a structure of type fcomplex, defined as:
struct fcomplex {double real, double imaginary};
offset(bytes) information data-type
100 x1 double /* coordinates */
108 y1 double
116 l1 double
100+(n-1)*24 x_n double
100+(n-1)*24+8 y_n double
100+(n-1)*24+16 l_n double
-------------- Repeated for each element.
100+24*elements Voltage1 fcomplex /* voltage */
100+24*elements+(n-1)*16 Voltage_n fcomplex
-------------- Repeated for each element n at each frequency step f.
100+40*elements Current1@f1 fcomplex /* current */
100+40*elements+(n-1)*16 Current_n@f1 fcomplex
100+56*elements Current@f2 fcomplex
100+40*elements+(n-1)*16 Current_n@f2 fcomplex
