A novel approach for approximation of summation to integral with mid-point summation to speed up the spectral domain approach for shielded microstrip lines

This paper presents a new formula involving integral and derivatives of the function, to approximate the summation of a series to an integral with the mid point summation (MPS). The error in approximating the summation with the new formulation, using the same number of terms, converges an order of magnitude faster than the EMF. A general expression has been developed to evaluate the constants involved. Also, a general expression for the special...
