A new and accurate closed-form expression is introduced using least squares method (LSM) to

calculate propagation constant of substrate integrated waveguide (SIW) at its fundamental mode of operation. The derived equation is a function...

An error indicator of the discrete least squares method (DLSM) for 2D elastostatic problems is presented.

In the DLSM, the problem domain is discretized by distributed field nodes. The field nodes are used to

construct the trial...
