Abstract :
Based on Cheby¿shev´s technique, a very convenient and efficient formula for calculating the LP11 mode cutoff frequency is derived. It is applicable to arbitrary index profiles including discrete numerical data from index profile measurements. The implementation is simple enough to be carried out easily on any pocket calculator with satisfactory accuracy for engineering applications.
