A method for modeling diffraction includes constructing a theoretical model of the subject. A numerical method is then used to predict the output field that is created when an incident field is diffracted by the subject. The numerical method begins by computing the output field at the upper boundary of the substrate and then iterates upward through each of the subject's layers. Structurally simple layers are evaluated directly. More complex layers are discretized into slices. A finite difference scheme is performed for these layers using a recursive expansion of the field-current ratio that starts (or has a base case) at the lowermost slice. The combined evaluation, through all layers, creates a scattering matrix that is evaluated to determine the output field for the subject.

For courses that deal with media content, such as sound, music, photographic images, hand sketches, video, conventional techniques for automatically evaluating and grading assignments are generally ill-suited to direct evaluation of coursework submitted in media-rich form. Likewise, for courses whose subject includes programming, signal processing or other functionally-expressed designs that operate on, or are used to produce media content, conventional techniques are also ill-suited. Instead, it has been discovered that media-rich, indeed even expressive, content can be accommodated as, or as derivatives of, submissions using feature extraction and machine learning techniques. In this way, e.g., in on-line course offerings, even large numbers of students and student submissions may be accommodated in a scalable and uniform grading or scoring scheme. Likewise, large collections of coursework submissions (whether or not graded or scored) or media content more generally, may be efficiently browsed and grouped using techniques described herein.

In a system for transmitting/receiving information, each of users of terminals subjectively determines a direct evaluation value of a party that the user knows personally and so on. Since the direct evaluation value determined in this way changes depending on the subjective evaluation criterion, the direct evaluation value is not generated based on the single evaluation criterion. In view of this, a terminal device 100A according to the present invention prestores therein content evaluation values respectively corresponding to pieces of content data that are stored therein. When transmitting a piece of content data to a terminal device, the terminal device 100A generates an entity evaluation value of the terminal device that is a transmission destination based on a content evaluation value of the transmitted piece of content data.
