Some idea as to the simulative precision of the propagation constant 

 r=A+iB of the "principal simulative loaded line" can be obtained 

 from Fig. 22 in Appendix A. For the present purf)ose the graphs 

 for X = can be regarded as pertaining exactly to the "principal simu- 

 lative loaded line" corresponding to any non-dissipative periodically 

 loaded line having any amount of distributed inductance, while the 

 graphs for X = 0.r2 are for any non-dissipative loaded line having 

 the particular inductance ratio X = 0.12. Of course, A is zero in the 

 range 0<r< 1.

Nktwdrks for Simli_\ting and for Compensating the Impedance 

 OF Loaded Lines — General Considerations 



The remainder of the paper relates to the simulation and the com- 

 pensation of the impedance of periodically loaded lines by means of 

 the simulating and the compensating networks devised by the writer, 

 as mentioned in the latter part of the Introduction. 



The term "compensating network" requires at least a tentative 

 detinition. The compensating networks dealt with in the present 

 paper are of two types: reactance-compensators, and susceptance- 

 comfiensators. For the present they may be defined — rather nar- 

 rowly — with reference to the first transmitting band of non-dissipative 

 loaded lines, as follows: a reactance-compensator is a network that 

 neutralizes the characteristic reactance of the line and hence simu- 

 lates its complementary characteristic reactance; a susceptance- 

 compensator is a network that neutralizes the characteristic sus- 

 ceptance of the line and hence simulates its complementary character- 

 istic susceptance. 



As actually worded, this division (Part I\') of the paper pertains 

 mainly to the simulation of loaded lines; but with appropriate slight 

 changes of wording most of it pertains also to compensation. Com- 

 pensation is dealt with explicitly in portions of Farts \' anrl \'1II of 

 the paper.
