What are the losses in a transmission line? Transmission line structures have different loss mechanisms. The total PCB transmission line loss is calledinsertion loss (αt). It is the sum ofconductor loss (αc),dielectric loss (αd), radiation loss (αr), and leakage loss (αl). αt =...
A formula is presented for the dependence of the hysteresis loss on winding angle. The formula is used to determine the optimum winding angle.doi:10.1016/S0921-4534(98)00464-XLawrence DresnerPhysica C SuperconductivityL. Dresner, "Incomplete--Penetration hysteresis losses in transmission line cables...
Transmission line bolts, as integral components of the power system, bear the responsibility of maintaining the stability and safe operation of the lines. However, these bolts are exposed to harsh natural conditions such as strong winds and snowstorms, which can lead to defects like loosening or ...
Every signal interconnection is a transmission line. However, it is not necessary to treat every signal path as a transmission line. Two different rules of thumb—if a conductor should be treated as transmission line or not—are explained in Sect.7.2.1(frequency-domain) and Sect.7.2.2(time-...
line losses that reduce efficiency of a line. Factors previously unable to be considered in design can now be simulated. For example, designers are able to modify geometry, placement and size of grading devices. Instead of using 1.5 inch tubing for a grading ring, an option of 2 in tubing...
A portion of the power radiated by a source in the deep sound channeling accordingly remains within the channeling and encounters no acoustic losses by reflection from the surface and bottom. Because of the low transmission loss in the channeling, very long ranges can be obtained from a source ...

causing signal resonance and losses. One solution is to pull back the planes near the signal or stitch them to the ground plane with vias placed closely on either side of the signal trace. However, such stitching may slightly affect transmission line impedance and require tweaking the design a...
In this paper the total owning cost (TOC) formula with built-in environmental components is used to assess the relative economic benefit of a high-first-cost, low-loss transmission line unit versus one with a lower first cost and higher losses. The proposed methodology is applied on the ...
A circuit g, in this particular instance where it is essential that losses be taken into account, gives a very high impedance over a relatively narrow band of frequencies and a quite low impedance over a band of considerable width. This type of shunt line section circuit is very satisfactory...
