- the amplitude guides separated eventually by rectilinear porof the TEowave is proportional to tions.
- the pointsto be connected may be, in par- ?r d ticular, the ends'of rectilinear guides.
- My novel system is characterized by the fact #1N/ 2- that every curved portion which it has is designed in such a manner as to cause the axisv of the guide to turn on the path in which it is inserted at an angle equal to the amplitudel of the wave TM1 being consev quently proportional to 1r d sin 2] '-50 1l/5 VR l nxslox in which expression: l t R'designates the bend curvature radius, degrees, n being any integer Whatever, x being the d the diameter of the right section of the guide, 35 length 0f a Wave Which COI'IeSDOIldS in a free I A the Wave length n free space of wave TEc, vand Space 00 the frequency transmitted by the guide.
