Dear All,

Check this website. It is free, as it is under testing. imodelit provides online tools for microwaves and optics components.

Please, send your comments on the website, applets, categories, shareware,... Feel free to send your feedback. Thanks in advance.

Best Regards,

Greetings imodelit_moderator:

That is a very nice website you have there :smt023. The user interface for the Java applets is one of the best I have seen - the output graphs with moving cursor readouts are a good touch. I highly recommend anyone reading this post visit your site. Being an amateur astronomer, I really appreciate the telescope optics calculators.

I added your website to my "Engineering Calculators & Converter Applets" page, and also added a link to the RF Cafe homepage in the "Recent Additions" column.

Incidently, I registered as a user, but then when clicked on the "Applet subscription" link to subscriber, I got an error message.

I looks fairly good and useful for the persons who will be working in the respective fields. I think you can also extend it to include some more designs like filters etc ...
