Hello, I want to create a diffraction order in using livelink in matlab. I could not find a command that describe how to create it. pasted bellow my lines of code in matlab:

%%%%% Assign Boundary Variables%%%%%% bL = 1; % left boundary -> inpot port bR = 12; % right boundary -> output port bB = 2; % bottom boundary -> periodic (Floquet) bT = 3; % top boundary -> periodic (Floquet)

%%%% Floquet periodic BC (y-direction) %%%%

pc1 = ewfd.create('pc1','PeriodicCondition',1); pc1.selection.set([bB, bT]); pc1.set('PeriodicType','Floquet'); pc1.set('kFloquet', {'k0cos(theta)', 'k0sin(theta)', '0'});

%%% input port (left) %%% port1 = ewfd.create('port1','Port',1); port1.selection.set(bL); port1.set('PortType','Periodic'); % port1.set('ModeType','PlaneWave'); port1.set('PortExcitation','on'); port1.set('E0', {'0','1','0'}); % Ey polarization doR1 = port2.create('doR1','DiffractionOrder',1); doR1.set('m',1); doR1.set('n', 0);

%%% output port (right) %%% port2 = ewfd.create('port2','Port',1); port2.selection.set(bR); port2.set('PortType','Periodic'); port2.set('ModeType','PlaneWave'); port2.set('PortExcitation','on'); doT1 = port2.create('doT1','DiffractionOrder',2); doT1.set('m', 1); doT1.set('n', 0);

Discussion Forum Rules and Guidelines

The goal of COMSOL Access is to provide a forum for you to communicate effectively with COMSOL as well as your colleagues within the multiphysics simulation community. This involves providing you with access to technical support and downloads of the latest {:comsol} software releases, as well as the ability to share your comments and work with other users of the {:comsol} software through forums such as the blog, discussion forum, and Application Exchange. In order to make this an efficient and pleasant experience for you and other members of COMSOL Access, we ask that you follow a few rules and guidelines.

Basic Rules

Flaming: Do not post any messages that harass, insult, belittle, threaten, or flame another member or guest. Debates are fine, but argue with the point, not the person.
Trolling: Do not post with the purpose of starting a dispute. Note that a person disagreeing with your opinion is not considered trolling; keep it civil, even if you are sure that the other person is wrong. Anything seen as trolling will result in you being banned.
Spamming: Posts without content or containing nonsense waste space and everyone's time. Spam will be removed from the forum.
Offensive Posts, Links or Images: Do not use profanity, racial, ethnic, religious, or other slurs or any other offensive material.

This includes posting contents of emails and private messages without the sender's consent. Do not bring personal disputes into the forums. Bans and warnings issued to other users are considered personal information.
Misleading Titles: The subject line of the post should be as informative as possible about the content of the post. This also reduces the amount of duplicate posts.
Thread Hijacking: Taking a thread off-topic to pursue one's own agenda is not permitted.
Piracy: Do not upload, post, email, transmit, or otherwise make available any content that infringes upon any patent, trademark, trade secret, copyright, or other proprietary rights ("Rights") of any party. This includes COMSOL model files created by a forged or illegitimate license.

You agree to comply with all rules applicable to each service you access through your COMSOL Access account.

Posting Guidelines

When posting, understand that you are trying to communicate with other people. Although many COMSOL Access members are not fluent in English, the official language of this forum is English.

Here are some important guidelines of language:

Write in English.
If you are familiar with LaTeX, please use this to write mathematical equations.
Always do a quick check for spelling/grammar mistakes.
Format your post in a legible manner. Use the Preview button often.

Use correct punctuation. Avoid run-on sentences.
Try to avoid using “text speak”, “net speak”, or slang. The purpose of language is to be understood.
Never invent acronyms and use as few acronyms as possible. For example, write "COMSOL Multiphysics" and not "CMP".
Review your post before publishing it. Try to catch typos.
Please check to see if a topic has already been posted. Do not post multiple threads on the same topic.
