The TDR instrument sends a pulse through the medium and compares the reflections from the unknown transmission environment to those produced by a standard impedance. 10页，共47页，星期一。

The Reflection CoefficientTDR measurements are described in terms of a Reflection Coefficient, (rho). The coefficient r is the ratio of the reflected pulse amplitude to the incident pulse amplitude:11页，共47页，星期一12页，共47页，星期一Calculating the Impedance of the Transmission Line and the Load13页，共47页，星期一Short and open circuit terminations14页，共47页，星期一Matched and mismatched load terminations15页，共47页，星期一Capacitive and inductive load terminations16页，共47页，星期一Capacitive and inductive discontinuities17页，共47页，星期一。

E and H fields being phasor quantities will be Complex Vector (CVc). The only exception to this rule is the Poynting input, Which will show up as a “CVc” even though E X H* should have no imaginary component. The calculator only knows that two complex vector were crossed, and does not know ahead of time that the imaginary component has been zeroed.26页，共47页，星期一。

HFSS Field Calculator: Detail Layout-StackAs data is entered into the calculator it appears at the TOP of the stack, pushing older entries DOWNUNDO attempts to take back the last operation between stack enties. It may not work for all data types (e.g. the result of a pure math operation cannot be reversed)CLEAR deletes ALL entries from the stack upon confirmationEXCH exchanges or swaps the top two stack entriesPUSH duplicates the top stack entryPOP deletes the top entry off the stackRLDN “rolls” the stack downward, moving the top entry to the bottomRLUP “rolls” the stack upward, moving the bottom entry to the top27页，共47页，星期一。
